CVE-2026-13221

CVE-2026-13221 affects Perl versions through 5.43.9. When an alternation of more than 65,535 fixed-string branches is compiled into a trie in Perl_study_chunk, the 16‑bit delta between the first branch and the shared tail overflows. The trie’s match decision table is truncated with no warning, pr...

PYSEC-2026-2745 Open WebUI: Read-Only Users Can Toggle Note Pin Status via Incorrect Permission Check (Write via Read-Only Access)

Summary The POST /api/v1/notes/id/pin endpoint performs a write operation toggling the ispinned field but only checks for read permission. Users with read-only access to a shared note can pin/unpin it, which is a state-modifying action that should require write permission. All other write endpoin...

PYSEC-2026-3044 pyzipper has an encryption bypass for small files encrypted using it

Impact A Python operator precedence bug in pyzipper/zipfileaes.py caused the AE-2 format to never be automatically selected during encryption, regardless of file size or compression type. As a result, all encrypted entries are written in AE-1 format unless AE-2 is explicitly forced by the caller...

⚡ Weekly Recap: ShareFile Threat, Citrix Bleed 2 Ransomware, AI Coding Attacks, and More

Somewhere right now, a security tool is quietly finding bugs faster than any human can fix them. That's supposed to be the good news. The catch is that the attackers have the same tools, pointed the other way, and they don't file tickets. That's the shape of this week. Trusted code turns on the...

PYSEC-2026-3394 UEFI Firmware Parser has a heap out-of-bounds write in tiano decompressor ReadCLen

uefi-firmware contains a heap out-of-bounds write vulnerability in the native tiano/EFI decompressor. in uefifirmware/compression/Tiano/Decompress.c, ReadCLen reads Number = GetBitsSd, CBIT with CBIT = 9, so Number can be as large as 511, while the destination array Sd-mCLen has NC = 510 elements...

PYSEC-2026-2849 OpenEXR has heap-buffer-overflow via signed integer underflow in ImfContextInit.cpp

Summary A heap-buffer-overflow OOB read occurs in the istreamnonparallelread function in ImfContextInit.cpp when parsing a malformed EXR file through a memory-mapped IStream. A signed integer subtraction produces a negative value that is implicitly converted to sizet, resulting in a massive lengt...
