{"cve":"CVE-2026-22187","nvd":{"published":"2026-01-07T21:16:02.600","modified":"2026-10-08T16:17:11.110","status":"Analyzed","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.","cvss_v4":{"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},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-502"],"references":["https://docs.openmicroscopy.org/bio-formats/","https://seclists.org/fulldisclosure/2026/Jan/7","https://www.vulncheck.com/advisories/bio-formats-memoizer-unsafe-deserialization-via-bfmemo-cache-files"],"products":["openmicroscopy:bio-formats"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2026-22187","score":0.00512,"percentile":0.43369,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qjm3-cvp9-3jj3","url":"https://osv.dev/vulnerability/GHSA-qjm3-cvp9-3jj3","summary":"Bio-Formats performs unsafe Java deserialization of attacker-controlled memoization cache files (.bfmemo) during image processing","modified":"2026-02-03T03:16:04.929406Z","packages":[{"ecosystem":"Maven","name":"ome:pom-bio-formats","purl":"pkg:maven/ome/pom-bio-formats","ranges":["<=8.3.0"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
