CVE-2026-76078

Probo: Broken access control in public e-signature API

Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. Prior to version 0.224.0, the public Trust Center GraphQL API exposes acceptElectronicSignature and recordSigningEvent, both gated only by @authentication(required: PRESENT) @sessionOnly — any self-provisioned trust center identity can call them. The underlying esign.Service.AcceptSignature and esign.Service.recordEvent build the tenant scope from the client-supplied signatureId GID (coredata.NewScopeFromObjectID(req.SignatureID)) and load the signature by that GID. At no point do they verify that the signature belongs to the caller or that the caller's email matches the signature's SignerEmail. As a result, any authenticated trust-center visitor who possesses another visitor's signature GID can: (1) complete that visitor's NDA signature — overwriting signer name/IP/UA with attacker data and setting status to Accepted, which triggers the sealing worker to generate a completion certificate; (2) inject arbitrary audit-trail events into any signature's log. Both attacks defeat the non-repudiation and integrity guarantees of the e-signature system. This issue has been patched in version 0.224.0.

Probo: Unauthenticated cross-tenant and hidden-item disclosure via Query.node in the public Trust Center API

Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. Prior to version 0.224.0, the public Trust Center GraphQL API exposes Query.node(id:) with @authentication(required: OPTIONAL) — an unauthenticated internet visitor to any published trust center can call it. Six of its type branches — Organization, Framework, Audit, ThirdParty (subprocessor), TrustCenter, and TrustCenterReference — resolve the object with a tenant scope derived from the client-supplied GID itself (coredata.NewScopeFromObjectID(id)) and load it with a bare Get(scope, id) that performs no comparison to the current trust center's OrganizationID and no showOnTrustCenter/visibility check. (The Document and File branches, by contrast, correctly pass trustCenter.OrganizationID and check visibility). This issue has been patched in version 0.224.0.

ideon: Unauthenticated /api/links/preview endpoint is an open SSRF relay, and its IP blocklist misses the 0.0.0.0/:: unspecified-address bypass

ideon is a self-hosted visual workspace. Prior to version 0.9.5, ideon's link-preview endpoint requires no authentication at all and forwards any URL a caller supplies straight into a server-side fetch. The app does have a general-purpose SSRF guard (safeFetch/validateSafeUrl in src/app/lib/ssrf.ts), but this route sits behind no login check whatsoever, making it a fully open, anonymous URL-fetch relay - and the guard's IP blocklist itself has a gap that lets it reach the server's own loopback interface via the 0.0.0.0 "any address" bypass, a well-documented SSRF-filter evasion technique on Linux. This issue has been patched in version 0.9.5.

Heym - Horizontal IDOR: get-by-id on workflow/node templates skips the visibility check the list path enforces

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, get_workflow_template / get_node_template fetches a template by ID with no visibility / author / shared_with predicate, so any authenticated user can read (and use) any other tenant's private (visibility=specific_users) template — including its full node/edge graph and the email addresses it was shared with. The list endpoint enforces visibility correctly; the single-item get/use paths do not. This issue has been patched in version 0.0.70.

Heym: Missing role gate in team-member management lets any member add/remove members, exposing team-shared credentials

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, team-member management (add / remove / update) is gated only on team membership, not on the team creator/admin role — and TeamMember has no role column. Any non-creator member can seat an attacker account into the team; because credential team-shares are scoped only by TeamMember.user_id, the newly-added attacker can then decrypt every credential shared into that team (provider API keys, OAuth tokens. This issue has been patched in version 0.0.70.

Heym Unsandboxed skill code execution: skills run via a local backend subprocess without the Docker isolation that Python tools mandate

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, heym hardens one untrusted-code path but not its sibling. The Python tool executor (python_tool_executor.py) treats user code as untrusted and mandates a Docker sandbox (no network, read-only fs, non-root, no docker socket), failing closed. The skill executor (skill_python_executor.py) runs skill Python via a local backend subprocess with no Docker isolation — only a 512 MB RLIMIT and a 7-key env denylist — so a skill executes inside the backend execution context, with filesystem access, network egress, and non-denylisted environment variables that should not be exposed to untrusted/shared skills. In the shipped Docker config (backend runs as root + /var/run/docker.sock mounted), this escalates to host root. This issue has been patched in version 0.0.70.

Heym: Playwright Custom Code Backend RCE via `playwrightCode` Field

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.71, Heym's workflow engine accepts an arbitrary Python code string in the playwrightCode field of a Playwright node. This string is written to a temporary .py file and executed directly by the backend process via subprocess.Popen([sys.executable, script_path]) with no sandboxing, AST validation, or role gate. Any authenticated user — including a freshly registered account — can achieve full remote code execution (RCE) on the backend host, running as the service process user (observed as root in the default Docker deployment). This issue has been patched in version 0.0.71.

Heym: Command execution via POST /api/mcp/fetch-tools stdio transport: supplied command is spawned before MCP validation

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.75, the same POST /api/mcp/fetch-tools endpoint (any authenticated user, lowest role) also accepts the stdio transport, which spawns the attacker-supplied command with attacker-supplied args and an environment merged over os.environ. The process executes on the shared backend host before MCP protocol validation fails — so side effects fire regardless of whether the command speaks MCP. This is a distinct weakness class and exploit primitive from the SSRF (Advisory 2) on the same endpoint, and needs a different fix (role gating / opt-in trust boundary rather than egress controls). This issue has been patched in version 0.0.75.

fulgur: Unbounded counters() expansion in generated content causes memory/CPU exhaustion (denial of service)

fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. From version 0.15.0 to before version 0.27.0, resolving the CSS counters(name, sep) function in generated content was bounded neither in the size of a single expansion nor in the aggregate work across an element tree. An attacker able to submit HTML/CSS to a fulgur-based conversion service can trigger CPU and memory exhaustion with a trivially small payload, denying service to the host and any co-tenants. This issue has been patched in version 0.27.0.

Open Redirect in MISP Modules Website Login via Unvalidated next Parameter

The MISP Modules website component contains an open redirect vulnerability in its login endpoint. The /login route accepted a user-supplied next query parameter and passed it directly to Flask's redirect() function without validating the destination. An attacker could craft a URL such as https://victim-host/login?next=https://attacker.example/phish and deliver it to a user (e.g., via email or a lookalike page). After the user successfully authenticated, the application issued a 302 redirect to the attacker-controlled external URL. This enables phishing attacks where a user, believing they are still on the legitimate MISP Modules site, may enter additional credentials or sensitive information on the attacker's page. It can also be used to obscure the true destination of a link, bypassing user trust in the legitimate domain. The vulnerability requires the victim to interact with the crafted URL and complete a login, but no prior authentication or special configuration is needed on the attacker's side. The affected component is the website sub-project of misp-modules, specifically the account blueprint in website/app/account/account.py. No version boundaries are specified in the patch metadata.

Algernon: Case-insensitive filesystem lets unauthenticated requests bypass /admin,/repo,/data permission-prefix gate

Algernon is a small self-contained pure-Go web server. Prior to version 1.17.10, Algernon's URL-prefix authorization gate matches its protected prefixes (/admin, /repo, /data) with case-sensitive strings.HasPrefix, while the exact same raw req.URL.Path is later resolved against the filesystem. On case-insensitive filesystems (Windows NTFS — always; macOS APFS/HFS+ — default), a request for /Admin/secret.lua evades every protected-prefix check, falls through to the public-prefix accept branch, and then resolves on disk to admin/secret.lua. The result is an unauthenticated bypass of the /admin, /repo, and /data authorization boundary, enabling read (and, for Lua files, execution) of protected content. The permission system is active in the default configuration. This issue has been patched in version 1.17.10.

OWASP CRS: XML Attribute Value Bypass

The OWASP core rule set (CRS) is a set of generic attack detection rules for use with compatible web application firewalls. Prior to versions 3.3.10, 4.25.1, and 4.28.0, CRS rules in the 921 (protocol-attack), 930 (LFI), 931 (RFI), 932 (RCE), 933 (PHP), 934 (generic), 941 (XSS), 942 (SQLi), and 943 (session-fixation) families inspect XML request bodies via the XPath expression XML:/*. That expression matches only element text nodes — it does not match XML attribute values. As a result, an attacker who places an attack payload inside an XML attribute (e.g. <a href="javascript:alert(1)=window.name"></a> or <a value="' OR 1=1 --"></a>) bypasses CRS detection entirely. This is verified empirically against a local CRS test instance and against the public CRS sandbox. The bypass affects approximately 159 rules across 9 rule files and applies at every paranoia level (PL1 through PL4), since the variable list is more or less shared across PLs. The 944 (Java) family is the only one that correctly includes XML://@* in addition to XML:/* and is therefore unaffected. This issue has been patched in versions 3.3.10, 4.25.1, and 4.28.0.

OWASP CRS: ReDoS in shared unix-shell-evasion regex-assembly include (12 RCE rules) - PCRE2 backtracking-limit exhaustion causes detection bypass and CPU DoS

The OWASP core rule set (CRS) is a set of generic attack detection rules for use with compatible web application firewalls. Prior to versions 3.3.10, 4.25.1, and 4.28.0, regular-expression denial of service (ReDoS) affects a shared regex-assembly include used to build 12 Unix RCE detection rules in CRS v4, and the same ambiguous pattern was present in the manually-assembled regexes in 4 rules in CRS v3.3. With a single, unauthenticated, crafted request, the generated pattern drives PCRE2 past its backtracking limit. When PCRE2 exceeds that limit, the @rx operator returns an error rather than a match result, which results in detection bypass and CPU denial of service. This issue has been patched in versions 3.3.10, 4.25.1, and 4.28.0.

Probo: Cross-tenant IDOR via unvalidated FK references

Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. Prior to version 0.223.1, Probo's console GraphQL API is a multi-tenant GRC platform where all data is scoped to an organization. A Finding can reference a Risk via finding.riskId. That reference is stored without validating that the risk belongs to the caller's organization, and the Finding.risk field resolver authorizes the finding (caller's org) instead of the risk, then loads the risk with a tenant scope derived from the risk's own global ID. As a result, an authenticated member of organization A can attach an arbitrary organization B risk GID to a finding they own and then read organization B's Risk (name, description, treatment, category, severity, owner) — with no membership in B. The stored cross-tenant reference also blocks B from deleting its own risk (ON DELETE RESTRICT), a cross-tenant integrity/DoS. This issue has been patched in version 0.223.1.
