Published : May 19, 2026, 7:16 a.m. | 1 hour, 41 minutes ago
Description :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.
