CVE-2026-1261883.7 BAJ—
———Active Storage makes it simple to upload and reference files in cloud services and attach those files to Active Record objects. Prior to 8.0.5.2 and from 8.1 until 8.1.4.1, Active Storage's ActiveStorage::Previewer::VideoPreviewer, ActiveStorage::Analyzer::VideoAnalyzer, and ActiveStorage::Analyzer::AudioAnalyzer pass uploaded blob contents to FFmpeg without restricting the demuxer. A direct upload can retain a client-declared video/* or audio/* content type for an HLS playlist. FFmpeg content probing selects the hls demuxer, which opens attacker-named file:// segments when the blob is previewed or analyzed. Applications that accept untrusted uploads and generate video previews or analyze video or audio attachments can disclose a local media file readable by the application process when the attacker knows its path. This issue is fixed in versions 8.0.5.2 and 8.1.4.1.7hCVE-2026-1260776.8 MED—
———Action Pack is a framework for handling and responding to web requests. Prior to 8.1.4.1 and 8.0.5.2, When ActionDispatch::Cookies reads a signed or encrypted cookie that was written under a rotated secret (config.action_dispatch.cookies_rotations) or in the format that a :hybrid cookie serializer migrates from, it writes the cookie back to the response in the current format, and that write ignores request.session_options[:skip]. ActiveStorage::DisableSession relies on that option to keep the session cookie off the public, immutable responses of the Active Storage proxy controllers, but those controllers still load the session, so a request carrying an old-format session cookie could receive the rewritten session cookie in Set-Cookie on a cacheable response. A shared cache that stores such a response together with its Set-Cookie header could then serve one user's session to later requesters of the same URL, or serve an attacker's session to other users. Applications are affected when they serve Active Storage files through the proxy controllers, have a cookie rotation or a :hybrid serializer migration configured, and run behind a cache that stores Set-Cookie on public responses. This is a path around the fix for CVE-2024-26144. This issue is fixed in versions 8.1.4.1 and 8.0.5.2.10hCVE-2026-961565.5 MED—
——0Use of uninitialized resource in Windows Broker Infrastructure Service allows an authorized attacker to disclose information locally.5hCVE-2026-125329——
——0Kaneo is a project management application with boards, Gantt charts, and GitHub integration that can be self-hosted or used as a cloud service. Prior to 2.13.0, GET /api/external-link/task/:taskId returns integration.config to any workspace member, including the viewer role, when a task has a linked Gitea issue or pull request. The plaintext integration.config contains the Gitea accessToken and webhookSecret, allowing the token's granted Gitea actions and forged webhook deliveries that pass HMAC verification. GitHub integrations and installations without a configured Gitea integration are not affected. This issue is fixed in version 2.13.0.10hCVE-2026-1094605.5 MED—
——0Exposure of sensitive information to an unauthorized actor in Microsoft Entra Private Network Connector allows an authorized attacker to disclose information locally.9hCVE-2026-33563——
——0Exposure of sensitive information to an unauthorized actor for some Intel(R) Platform Monitoring Technology (Intel(R) PMT) software before version 3.2.0.22 within Ring 3: User Applications may allow an information disclosure. System software adversary with an authenticated user combined with a low complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.9h
