CVE-2026-65605 SiYuan before v3.7.2 Stored XSS to RCE via Attribute View

SiYuan before v3.7.2 contains a stored cross-site scripting vulnerability in Attribute View database cell rendering. A Template column value is rendered as HTML via text/template without auto-escaping, and EscapeHTML is only applied when HasUnclosedHtmlTag returns true; because balanced...

CVE-2026-65605

SiYuan prior to v3.7.2 is vulnerable to a stored XSS in the Attribute View (database) cell rendering. A Template column value is rendered as HTML via text/template without auto-escaping, with EscapeHTML applied only when HasUnclosedHtmlTag is true; balanced self-closing tags like can bypass this...

Pillow: Decompression Bomb DoS via PdfParser.PdfStream.decode()

SummaryPdfParser.PdfStream.decode in Pillow's PdfParser.py calls zlib.decompress with the bufsize parameter set to the value of the PDF stream's Length field, without any upper bound on the actual decompressed output size. Python's zlib.decompress bufsize argument is an initial output buffer hint...

LiteLLM: Arbitrary file write via path traversal in Skills archive extraction

ImpactLiteLLM Skills archive extraction did not sufficiently validate file paths from uploaded skill ZIP archives. An authenticated user with access to LiteLLM LLM API routes, or a key whose allowedroutes includes /v1/skills, anthropicroutes, or llmapiroutes, could upload a crafted skill archive...

Pillow: Out-of-bounds read via attacker-controlled row stride on Pillow's mmap path (McIdas AREA files)

SummaryWhen Pillow loads an uncompressed image whose tile uses the raw codec and a mode in Image.MAPMODES, and the image was opened from a filename, it memory-maps the file and builds the image's row pointers directly into the mapping via PyImagingMapBuffer src/map.c. The per-row spacing stride i...

LightRAG is Vulnerable to Authentication Bypass: hardcoded DEFAULT_TOKEN_SECRET and public /auth-status defeat LIGHTRAG_API_KEY protection

SummaryWhen LightRAG is deployed with LIGHTRAGAPIKEY set but AUTHACCOUNTS unset an officially documented "API-Key authentication" mode, the X-API-Key protection can be bypassed by any remote unauthenticated attacker. The bypass does not require network contact with the victim server — an attacker...
