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.","state":0,"publishedAt":"2026-01-07T20:27:06.679+00:00","modifiedAt":"2026-10-08T15:22:15.847+00:00","affected":[{"ecosystem":"Vendor product","name":"Bio-Formats","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Bio-Formats\",\n                    \"vendor\": \"Open Microscopy Environment\",\n                    \"versions\": [\n                        {\n                            \"lessThanOrEqual\": \"8.3.0\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:maven/ome/pom-bio-formats\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","score":6.8,"severity":"MEDIUM"}],"references":["https://seclists.org/fulldisclosure/2026/Jan/7","https://docs.openmicroscopy.org/bio-formats/","https://www.vulncheck.com/advisories/bio-formats-memoizer-unsafe-deserialization-via-bfmemo-cache-files"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-22187","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-22187","identifiers":["CVE-2026-22187"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
