In SQLite 3.27.2, running fts5 prefix queries inside a transaction could trigger a heap-based buffer over-read in fts5HashEntrySort in sqlite3.c, which may lead to an information leak. This is related to ext/fts5/fts5_hash.c.
AnalysisAI
In SQLite 3.27.2, running fts5 prefix queries inside a transaction could trigger a heap-based buffer over-read in fts5HashEntrySort in sqlite3.c, which may lead to an information leak. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Out-of-bounds Read vulnerability could allow attackers to read data from memory outside the intended buffer boundaries.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. In SQLite 3.27.2, running fts5 prefix queries inside a transaction could trigger a heap-based buffer over-read in fts5HashEntrySort in sqlite3.c, which may lead to an information leak. This is related to ext/fts5/fts5_hash.c. Affected products include: Sqlite.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
