HIGHopenmicroscopy/bio-formats <= 8.3.0 - Deserialization of Untrusted Data via Memoization Cache Files
Title source: llmExploitation Summary
EIP tracks 2 public exploits for CVE-2026-22187. PoCs published by XiaomingX, George0Papasotiriou.
AI-analyzed exploit summary The repository contains a functional PoC demonstrating unsafe Java deserialization in Bio-Formats via .bfmemo files. The code shows the deserialization path is executed without malicious payloads, confirming the vulnerability.
Description
Bio-Formats versions up to and including 8.3.0 perform unsafe Java deserialization of attacker-controlled memoization cache files (.bfmemo) during image processing. The loci.formats.Memoizer class automatically loads and deserializes memo files associated with images without validation, integrity checks, or trust enforcement. An attacker who can supply a crafted .bfmemo file alongside an image can trigger deserialization of untrusted data, which may result in denial of service, logic manipulation, or potentially remote code execution in environments where suitable gadget chains are present on the classpath.
