CVE-2026-22187 Details
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.
A vulnerability exists in Bio-Formats versions through 8.3.0, where unsafe Java deserialization of attacker-controlled memoization cache files (.bfmemo) occurs during image processing. The loci.formats.Memoizer class automatically loads and deserializes these memo files without any validation or integrity checks. This flaw allows an attacker to supply a crafted .bfmemo file, triggering the deserialization of untrusted data. The consequences can include denial-of-service, manipulation of application logic, or potentially remote code execution, especially in environments where suitable gadget chains are available on the classpath.
