Exponential catastrophic backtracking (ReDoS) in marked

Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression `inline.reflinkSearch` may cause catastrophic backtracking against some strings and lead to a denial of service (DoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources.

OpenClaw < 2026.5.12 - Allowlist Bypass via PowerShell Encoded-Command Aliases

OpenClaw before 2026.5.12 contains an allowlist bypass vulnerability in PowerShell encoded-command handling that allows attackers to execute encoded commands using abbreviated flag aliases not recognized by the allowlist parser. Remote authenticated operators can bypass execution allowlist checks by using unrecognized encoded-command alias forms to execute arbitrary PowerShell content.

vm2: NodeVM builtin denylist bypass via process and inspector/promises allows host code execution

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM blocks several dangerous Node.js builtins such as module, worker_threads, cluster, vm, repl, and inspector. However, the denylist misses process and inspector/promises. Both can be used from sandboxed code to reach host-side execution primitives. This allows sandboxed code to bypass the intended builtin restrictions and execute code in the host process. This issue has been patched in version 3.11.4.

Fedify has an LD-Signature Bypass via JSON-LD Named-Graph Restructuring

Fedify is a TypeScript library for building federated server apps powered by ActivityPub. Prior to versions 1.9.11, 1.10.10, 2.0.18, 2.1.14, and 2.2.3, an attacker can make use of JSON-LD features to restructure a JSON-LD document that would change how Fedify interprets it without changing its Linked Data Signature, allowing them to alter a third-party signed activity they have received. Versions 1.9.11, 1.10.10, 2.0.18, 2.1.14, and 2.2.3 fix the issue.

cilium ebpf LoadCollectionSpec/LoadCollectionSpecFromReader btf.go loadRawSpec integer overflow

A vulnerability has been found in cilium ebpf up to 0.21.0. This affects the function loadRawSpec of the file btf/btf.go of the component LoadCollectionSpec/LoadCollectionSpecFromReader. Such manipulation of the argument offset leads to integer overflow. The attack can only be performed from a local environment. The exploit has been disclosed to the public and may be used. The name of the patch is 533dfc82fd228bfadf42ea7180c39de7d9af47fa. A patch should be applied to remediate this issue.

HAX open-apis: Credential Theft via Server-Side Request Forgery (SSRF) in open-apis

HAX CMS helps manage microsite universe with PHP or NodeJs backends. Starting in version 9.0.1 and prior to version 26.0.0 of @haxtheweb/open-apis, multiple functions conduct substring-only matching to validate hostnames to which basic authorization should be sent. An attacker can append the matched substrings to an attacker-controlled endpoint and capture authentication. Version 26.0.0 fixes the issue.

chromium-browser: Inappropriate implementation in Safe Browsing

Inappropriate implementation in Safe Browsing in Google Chrome on Mac prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code via a malicious file. (Chromium security severity: Low)

Linaro/OP-TEE OP-TEE 3.3.0 and earlier is affected by: Rounding error. The impact is: Potentially leaking code and/or data from previous Trusted Application. The component is: optee_os. The fixed version is: 3.4.0 and later.

go-git: Improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git

go-git is an extensible git implementation library written in pure Go. Prior to 5.19.0 and 6.0.0-alpha.3, go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object. Additionally, go-git’s commit signing and verification logic operates over commit data reconstructed from go-git’s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository. This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed. This vulnerability is fixed in 5.19.0 and 6.0.0-alpha.3.

Zed: Allowlist Bypass via Environment Variable Injection in Terminal Tool Permissions

Zed is a code editor. Prior to 0.229.0, Zed's terminal tool permission system can be bypassed by prepending environment variable assignments to allowlisted commands, hijacking program behavior (e.g., PAGER) to execute arbitrary code. This vulnerability is fixed in 0.229.0.

Zed: Allowlist Bypass via Bash Variable Expansion Chain in Terminal Tool Permissions

Zed is a code editor. Prior to 0.229.0, Zed's terminal tool permission system can be bypassed via bash variable expansion chaining (${var@P}), allowing arbitrary command execution under an allowlisted command prefix. This vulnerability is fixed in 0.229.0.

view_component: System Test Entry Point Path Check Allows Sibling Directory Escape

view_component is a framework for building reusable, testable, and encapsulated view components in Ruby on Rails. From 3.0.0 to 4.9.0, the system test entrypoint canonicalizes a user-controlled file path with File.realpath, then checks whether the resolved path starts with the temp directory path. This is not a safe containment check because sibling directories can share the same string prefix. This vulnerability is fixed in 4.9.0.

Hono: IP Restriction bypasses static deny rules for non-canonical IPv6

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.21, the ip-restriction middleware (hono/ip-restriction) compares incoming IP addresses against configured deny and allow rules using string equality after partial normalization. Non-canonical IPv6 representations of an address already listed in a static rule — such as compressed forms, explicit-zero forms, or hex-notation IPv4-mapped addresses — do not match the normalized rule entry, causing the rule to be silently skipped. This vulnerability is fixed in 4.12.21.

janet-lang janet marsh.c unmarshal_one_fiber integer overflow

A weakness has been identified in janet-lang janet up to 1.41.0. This vulnerability affects the function unmarshal_one_fiber of the file src/core/marsh.c. Executing a manipulation can lead to integer overflow. It is possible to launch the attack on the local host. The exploit has been made available to the public and could be used for attacks. This patch is called d9b1d711ea1fde52ac73a82088b512a3e17bad0d. A patch should be applied to remediate this issue.

FastGPT: sandbox escape to RCE - code-sandbox regex /\bimport\s*\(/ is bypassable

FastGPT is an AI Agent building platform. Prior to 4.15.0-beta1, the JavaScript sandbox worker at projects/code-sandbox/src/pool/worker.ts:356 blocks dynamic import() with the regex /\bimport\s*\(/.test(code). JavaScript syntax accepts a block comment between import and (; the regex matches only ASCII whitespace, and the bytes /, *, *, / are not in the \s character class. The payload import/**/("child_process") parses as a syntactically valid dynamic import that the regex does not detect. Because import() is not wrapped by the safeRequire Proxy (which only proxies require), the attacker loads child_process and calls execSync - arbitrary command execution as uid=100(sandbox) inside the sandbox container. This vulnerability is fixed in 4.15.0-beta1.

Budibase: Unanchored Regex in `matchers.ts` Allows CSRF Bypass via Query String Injection in Budibase Worker

Budibase is an open-source low-code platform. Prior to 3.35.4, the buildMatcherRegex() / matches() functions in packages/backend-core/src/middleware/matchers.ts route patterns are compiled into unanchored regular expressions and tested against ctx.request.url, which includes the full query string. The CSRF middleware in the Budibase Worker uses this matching system to decide whether to skip CSRF token validation. An unauthenticated attacker can forge state-changing cross-origin requests against any Worker API endpoint by injecting a public route pattern into the query string, causing the CSRF middleware to skip token validation entirely. This allows actions such as sending admin invites, modifying global configuration, and managing users without a valid CSRF token. This vulnerability is fixed in 3.35.4.

IEC 60870-5-104 used in RTU500: Potential Denial of Service impact on reception of invalid U-format frame. Product is only affected if IEC 60870-5-104 bi-directional functionality is configured. Enabling secure communication following IEC 62351-3 does not remediate the vulnerability but mitigates the risk of exploitation.

OpenClaw < 2026.2.21 - Arbitrary File Read via grep -e Flag Policy Bypass

OpenClaw versions prior to 2026.2.21 contain a stdin-only policy bypass vulnerability in the grep tool within tools.exec.safeBins that allows attackers to read arbitrary files by supplying a pattern via the -e flag parameter. Attackers can include a positional filename operand to bypass file access restrictions and read sensitive files.env from the working directory.

Tekton Pipelines: VerificationPolicy regex pattern bypass via substring matching

Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. Starting in version 0.43.0 and prior to versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1, trusted resources verification policies match a resource source string (refSource.URI) against spec.resources[].pattern using regexp.MatchString. In Go, regexp.MatchString reports a match if the pattern matches anywhere in the string, so common unanchored patterns (including examples in tekton documentation) can be bypassed by attacker-controlled source strings that contain the trusted pattern as a substring. This can cause an unintended policy match and change which verification mode/keys apply. Versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1 fix the issue.
