{"schema":"threatline.record/2","record":{"id":"CVE-2026-108518","aliases":["GHSA-7393-6f8r-fhh3"],"summary":"DBI versions before 1.656 for Perl crash via type confusion in dbi_profile when a database handle is destroyed under a Profile Path with an {attr} element","details":"DBI versions before 1.656 for Perl crash via type confusion in dbi_profile when a database handle is destroyed under a Profile Path with an {attr} element.\n\nAn {attr} element names a database handle attribute, which dbi_profile reads from the handle's inner hash. It expects the inner handle as a reference and dereferences it, but a handle that is being destroyed hands back the inner hash itself, so the dereference yields the hash's bucket array. A type check on that pointer usually fails and the call goes unprofiled. When the memory it addresses passes the check, the attribute lookup dereferences a NULL or invalid pointer and the process dies on SIGSEGV.\n\nThe Path is set by the application, by the Profile handle attribute, or by the DBI_PROFILE environment variable, so `DBI_PROFILE={ImplementorClass}` can crash an unmodified program.","categories":["Unclassified"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-108518","source_modified_at":"2026-10-21T00:17:16.110Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":null,"vendor":null,"versions":[{"lessThan":"1.656","status":"affected","version":"0","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-108518","source_modified_at":"2026-10-21T00:17:16.110Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":null,"ecosystem":null},"version":"1.656","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00229,"percentile":0.12911,"score_date":"2026-10-23"},"published_at":"2026-10-20T21:23:13.373Z","modified_at":"2026-10-21T00:17:16.110Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-108518","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T00:17:16.110Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-108518","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/perl5-dbi/dbi/security/advisories/GHSA-7393-6f8r-fhh3","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://github.com/perl5-dbi/dbi/commit/c2ff4df575d7af625bb4d0d1ef7539f90b22d8b2.patch","tags":["patch"]},{"source":"CVE List","url":"https://metacpan.org/release/HMBRAND/DBI-1.656/changes","tags":["release-notes"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-21T00:17:16.110Z","content_hash":"cf0221f952fe466a0557e8049ef91276ba1f9276ce6d7367713fd810bb0ebad5"}}
