{"id":"BIT-sqlite-2026-11822","summary":"SQLite before 3.53.2 Memory Corruption in FTS5 Extension","details":"SQLite before 3.53.2 contains memory corruption vulnerabilities in the FTS5 full-text search extension that allow attackers to cause process crashes, memory exhaustion, or arbitrary code execution by supplying a crafted database with malformed FTS5 page data. Attackers can trigger an out-of-bounds read in fts5LeafSeek() via an attacker-controlled loop bound and a heap buffer overflow write in fts5ChunkIterate() through a crafted continuation page causing an integer underflow, exploitable when an FTS5 MATCH query is executed against the malicious database.","aliases":["CVE-2026-11822"],"modified":"2026-06-12T09:15:06.708150834Z","published":"2026-06-12T08:51:44.016Z","database_specific":{"cpes":["cpe:2.3:a:sqlite:sqlite:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11822"},{"type":"WEB","url":"https://sqlite.org/releaselog/3_53_2.html"},{"type":"WEB","url":"https://sqlite.org/src/info/061febcf41ca"},{"type":"WEB","url":"https://sqlite.org/src/info/4a5ad516ea93"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/sqlite-before-memory-corruption-in-fts5-extension"}],"affected":[{"package":{"name":"sqlite","ecosystem":"Bitnami","purl":"pkg:bitnami/sqlite"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.53.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/sqlite/BIT-sqlite-2026-11822.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.7.5"}
