CVE-2026-8814

5.5 mediumEPSS 0.5%

Medium (5.5). EPSS 0.5% chance of exploitation in the next 30 days. Fixed in exifreader 4.39.0.

Versions of the package exifreader before 4.39.0 are vulnerable to Improper Handling of Highly Compressed Data (Data Amplification) due to decompressing PNG zTXt metadata without enforcing a built-in maximum decompressed output size. When asynchronous parsing is enabled, a crafted PNG file containing a highly compressed zTXt chunk can cause ExifReader to materialize a disproportionately large Comment value in memory.
