Reliance on Untrusted Inputs in a Security Decision in GitLab

GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user holding a specific granular permission to obtain a GitLab Duo Agent Platform token that bypasses governance controls, due to reliance on untrusted input in a security decision.

drm/msm/snapshot: fix dumping of the unaligned regions

In the Linux kernel, the following vulnerability has been resolved: drm/msm/snapshot: fix dumping of the unaligned regions The snapshotting code internally aligns data segment to 16 bytes. This works fine for DPU code (where most of the regions are aligned), but fails for snapshotting of the DSI data (because DSI data region is shifted by 4 bytes). Fix the code by removing length alignment and by accurately printing last registers in the region. While reworking the code also fix the 16x memory overallocation in msm_disp_state_dump_regs().

A improper neutralization of script-related html tags in a web page (basic xss) vulnerability in Fortinet may allow attacker to execute unauthorized code or commands via network exploitable

Backstage: Scaffolder action input authorization bypass

Backstage is an open framework for building developer portals. Prior to 3.3.1, 3.4.1, 4.0.3 and 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by scaffolder action input authorization bypass. An authenticated user with access to affected Scaffolder templates could bypass configured action restrictions. Depending on integration credentials, this could grant unauthorized access to repositories and related source-control resources. This issue is fixed in versions 3.3.1, 3.4.1, 4.0.3 and 4.1.0.

pH7Builder before 19.3.0 CAPTCHA Bypass via Client-Chosen Form ID

pH7Builder (pH7 Social Dating CMS) before 19.3.0 contains a CAPTCHA bypass vulnerability that allows unauthenticated attackers to skip form validation by supplying a client-chosen form ID to PFBC Form::isValid(). Attackers can load a CAPTCHA-free form like login or search, then submit its ID with contact, comment, forum, invite or signup data to automate abuse.

Frappe before 13.46.1 XSS via html2text Weak Sanitization

Frappe before 13.46.1 and 14.x before 14.20.0 contains a cross-site scripting vulnerability because the html2text function weakly sanitizes user input. Authenticated attackers can supply crafted HTML that is insufficiently sanitized by html2text, executing scripts in the browsers of users who view the rendered content.

Kiteworks Core Remote Code Execution

On deployments where the remote-support capability is licensed and enabled, an authenticated System Administrator who also possessed the key protecting the submitted data could redirect the underlying system's outbound support connection to a destination of their choosing. That destination could then have operating-system commands executed on the node and receive their output, potentially resulting in remote code execution with the privileges of a local service account.

League CommonMark 1.3.0 before 2.10.2 Stored XSS via DisallowedRawHtml Bypass

League CommonMark from 1.3.0 before 2.10.2 contains a cross-site scripting vulnerability that allows users posting Markdown to bypass the DisallowedRawHtml extension by ending raw HTML with a bare disallowed tag name. Attackers can place a lone <script or <iframe line followed by a block supplying attributes like src or onload, executing stored scripts in viewers' browsers under default GFM settings.

Improper neutralization of Script-Related HTML tags in a web page (basic XSS) vulnerability in İzometri IT Services Domestic and Foreign Trade Co. Ltd. Eimzamip allows Stored XSS. This issue affects eimzamip: from v1.6.4 before v1.6.7.

Reliance on Untrusted Inputs in a Security Decision in hMailServer

The Linux live-update apply helper (hmailserver-update) of Progressive Robot hMailServer 6.3.4 and 6.3.5 runs as root on a request file written by the unprivileged hmailserver service account, and took from that request the program used to verify an AppImage update's signature and the systemd unit to stop before reading the service account's files. An attacker who already runs code as the hmailserver service account, for example through another flaw in the mail server, can therefore have arbitrary code executed as root, on any Linux installation where the live update's path unit is active - the default for the project's .deb and .rpm packages - and on AppImage installations run under that unit.

KaTeX: Existing prototype pollution can bypass trust restrictions

KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web. From 0.11.0 until 0.18.2, KaTeX uses ordinary JavaScript property access for the renderer options object, the trust setting, default and processor setting metadata, and namespace lookup and group restoration, allowing inherited properties to be treated as explicitly supplied values. When Object.prototype is already polluted or an attacker controls the options object's prototype, attacker-controlled mathematical expressions can use an inherited trust value to enable trusted rendering and produce links capable of user-interaction cross-site scripting or loading attacker-selected external resources in a consuming application that inserts unsanitized KaTeX output into a page. KaTeX does not itself create the prototype pollution, and rendering an expression alone does not execute script. This issue is fixed in version 0.18.2.

Joomla Extension - joomshaper.com - Unauthenticated CAPTCHA Bypass in Module Context in the Contact, Opt-in and Form Builder Addons in SP Page Builder Pro 3.2.6 - 5.6.1p2 and 6.0.0 - 6.9.0

Joomla Extension - joomshaper.com - Unauthenticated CAPTCHA Bypass in Module Context in the Contact, Opt-in and Form Builder Addons in SP Page Builder Pro 3.2.6 - 5.6.1p2 and 6.0.0 - 6.9.0 - In the ajax_contact, optin_form and form_builder addons, the result returned by the CAPTCHA plugin's onCheckAnswer event was discarded and replaced with a test for a non-empty string whenever the request-supplied view_type parameter equalled module. Submitting view_type=module together with any arbitrary token value therefore passed verification. This affected every instance of these addons placed inside an SP Page Builder module, irrespective of the CAPTCHA type configured for the site, and the view_type parameter was never validated against the context in which the form was actually rendered.

authentik: MFA Bypass via State Confusion / Parameter Injection in AuthenticatorEmailStage

authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, authentik email authenticator enrollment during an authentication or enrollment flow accepts a recipient address supplied in the setup request instead of using the address already established by the flow. An actor who knows a target user's password can substitute an attacker-controlled address, receive the one-time code, and finish enrolling the factor as the target. The target must not have enrolled the email factor already. Successful enrollment gives the actor a session as the target and access to single sign-on applications behind the account. Other authenticator types are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.

net: mpls: clear inner_protocol when the last label is popped

In the Linux kernel, the following vulnerability has been resolved: net: mpls: clear inner_protocol when the last label is popped skb_mpls_push() records the pre-encapsulation network header once, gated on !skb->inner_protocol. skb_mpls_pop() never clears that record, so it outlives the encapsulation it describes. Open vSwitch can then re-push MPLS onto a packet whose inner_network_header still points at the older, deeper offset: push a label, pop every label, recirculate (ovs_flow_key_update() re-derives key->eth.type and resets network_header, but leaves inner_*), then push again. ovs_fragment() trusts the record: skb->network_header = skb->inner_network_header; so skb_network_offset() goes negative. The bound check is signed: if (skb_network_offset(skb) > MAX_L2_LEN) a negative offset passes it, and prepare_frag() widens the value: unsigned int hlen = skb_network_offset(skb); memcpy(&data->l2_data, skb->data, hlen); which is a ~4GiB memcpy out of a 30-byte per-CPU buffer. Reproduced on v7.3-rc1. RDX is the truncated length, (unsigned int)(-8): BUG: unable to handle page fault for address: ffffe8ffffc16000 #PF: supervisor write access in kernel mode Oops: 0002 [#1] SMP KASAN NOPTI RIP: 0010:memcpy+0x8/0x20 RDX: 00000000fffffff8 RSI: ffff888105d732db RDI: ffffe8ffffc16000 prepare_frag+0x3df/0x4e0 ovs_fragment+0x589/0x7e0 do_output+0x4ce/0x5e0 do_execute_actions+0x55d2/0x7b30 ovs_execute_actions+0xea/0x450 Same root-cause shape as commit 975b5b067f52 ("ipv6: sr: restore network header before routing and forwarding"): a stale network header offset reaching a consumer that widens it. Here it originates in the MPLS push/pop path. Clear inner_protocol once the packet is no longer MPLS, so a later push re-records the current header. net/sched/act_mpls.c is the only other skb_mpls_pop() caller and gets the same fix; sch_frag.c saves and restores inner_protocol around fragmentation in the same way OVS does.
