When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams.","categories":["Unclassified"],"product":"Guava","vendor":"Google","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102554","source_modified_at":"2026-10-09T18:09:50.100Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Guava","vendor":"Google","versions":[{"lessThan":"33.7.2","status":"affected","version":"4.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","source_modified_at":"2026-09-29T14:31:05Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"maven","name":"com.google.guava:guava"},"range":"4.0–33.7.1"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102554","source_modified_at":"2026-10-09T18:09:50.100Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Guava","ecosystem":null},"version":"33.7.2","basis":"first unaffected version stated in the CVE record"},{"source":"GitHub Advisory Database","source_url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","source_modified_at":"2026-09-29T14:31:05Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"maven","name":"com.google.guava:guava"},"version":"33.7.2"}],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00352,"percentile":0.27624,"score_date":"2026-10-23"},"published_at":"2026-10-09T15:07:16.130Z","modified_at":"2026-10-09T18:09:50.100Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102554","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-09T18:09:50.100Z"},{"source":"GitHub Advisory Database","url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","fetched_at":"2026-10-24T00:31:04.721601Z","source_modified_at":"2026-09-29T14:31:05Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102554","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/google/guava/commit/b931fe9d6d5cf00bc55714ad3308d086f71850fe"},{"source":"CVE List","url":"https://github.com/google/guava/releases/tag/v33.7.2"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-09T18:09:30.467336Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-09T18:09:50.100Z","content_hash":"9ba3c775b7f85cd3479563bd5f6df53b21f3e416e69d704927340ae5b7974b0e"}}
