Missing Anti‑Frame Header Vulnerability in Ajenti UI Allows Clickjacking

ajenti through v2.2.13 has a clickjacking weakness in the browser-facing login and administrative UI. In ajenti-core/aj/http.py, the core HTTP response path initializes an empty header list, forwards handler-added headers verbatim, and finalizes responses through WSGI start_response() without adding anti-framing protections such as X-Frame-Options or a Content-Security-Policy frame-ancestors restriction.

CVE-2025-71377

stoatchat before 20250210-1 Unrestricted Message History Fetch

stoatchat (delta) versions before 20250210-1 (0.8.2) contain a logic error in the query messages route. When fetching messages 'nearby' another message, the database query can be given a message limit of zero, which the database interprets as 'no limit'. A remote unauthenticated attacker can craft nearby message fetch requests to download an entire channel's message history in a single expensive request, and can send many such requests in parallel, resulting in denial of service through resource exhaustion.

CVE-2026-59890

setuptools: MANIFEST.in exclusion bypass in sdist via Unicode normalization collision (NFC/NFD) on macOS APFS/HFS+

setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0.
