{"schema":"threatline.record/2","record":{"id":"CVE-2026-92705","aliases":["GHSA-67hq-5vgg-6f23"],"summary":"Aegisub executes arbitrary code through automatically loaded Automation scripts","details":"Aegisub is a cross-platform advanced subtitle editor. From 3.2.0 to 3.4.2, Aegisub automatically loads Automation scripts referenced by `Automation Scripts` metadata in `ASS` subtitle projects without asking whether the user trusts the scripts or their authors. An attacker can distribute a crafted `ASS` file together with a referenced malicious Automation script, and opening the `AS`  file executes arbitrary code with the privileges of the Aegisub process. From 3.4.0 to 3.4.2, inconsistent handling of embedded `NUL` characters between extension validation and filesystem operations additionally allows a crafted `ASS/Lua` polyglot to reference and execute itself as a single-file variant. The vulnerability is fixed in Aegisub 3.5.0.","categories":["Unclassified"],"product":"Aegisub","vendor":"TypesettingTools","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92705","source_modified_at":"2026-10-14T02:14:56.936Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Aegisub","vendor":"TypesettingTools","versions":[{"status":"affected","version":">= 3.2.0, < 3.5.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/TypesettingTools/Aegisub/security/advisories/GHSA-67hq-5vgg-6f23","source_modified_at":"2026-10-05T11:41:38Z","fetched_at":"2026-10-23T18:58:35.272684Z","package":{"ecosystem":"","name":"Aegisub"},"range":">= 3.2.0, <= 3.4.2"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/TypesettingTools/Aegisub/security/advisories/GHSA-67hq-5vgg-6f23","source_modified_at":"2026-10-05T11:41:38Z","fetched_at":"2026-10-23T18:58:35.272684Z","package":{"ecosystem":"","name":"Aegisub"},"version":"3.5.0"}],"cvss":7.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0013,"percentile":0.02386,"score_date":"2026-10-23"},"published_at":"2026-10-09T20:37:58.321Z","modified_at":"2026-10-14T02:14:56.936Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92705","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T02:14:56.936Z"},{"source":"GitHub Advisory Database","url":"https://github.com/TypesettingTools/Aegisub/security/advisories/GHSA-67hq-5vgg-6f23","fetched_at":"2026-10-23T18:58:35.272684Z","source_modified_at":"2026-10-05T11:41:38Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92705","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/TypesettingTools/Aegisub/security/advisories/GHSA-67hq-5vgg-6f23","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/TypesettingTools/Aegisub/commit/0a3073d59f10432eeebea65018b02ef4d0a87fff","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/TypesettingTools/Aegisub/commit/b5bf23979e7453f7b1cc8ffeb82b3cc2d2ca75e6","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/TypesettingTools/Aegisub/commit/e4099055711cce327840870c050ce46e58f4aee0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-14T02:14:47.778335Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T02:14:56.936Z","content_hash":"e01dc42aa9864cbde37b5bdbd2904411bea7eee8ea41a4141aedfe580988ed58"}}
