CVE-2026-27809 (GCVE-0-2026-27809)

Vulnerability from cvelistv5 – Published: 2026-02-25 23:57 – Updated: 2026-02-26 15:17

Title
psd-tools: Compression module has unguarded zlib decompression, missing dimension validation, and hardening gaps
Summary
psd-tools is a Python package for working with Adobe Photoshop PSD files. Prior to version 1.12.2, when a PSD file contains malformed RLE-compressed image data (e.g. a literal run that extends past the expected row size), decode_rle() raises ValueError which propagated all the way to the user, crashing psd.composite() and psd-tools export. decompress() already had a fallback that replaces failed channels with black pixels when result is None, but it never triggered because the ValueError from decode_rle() was not caught. The fix in version 1.12.2 wraps the decode_rle() call in a try/except so the existing fallback handles the error gracefully.
Severity ?
