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.

SQLite before 3.53.2 contains a heap-based buffer overflow vulnerability in the FTS5 full-text search extension that allows attackers to cause a crash or execute arbitrary code by supplying a crafted database with malicious continuation page metadata specifying a szLeaf value smaller than 4. Attackers can trigger an integer underflow in fts5ChunkIterate() causing an inflated remaining byte count during FTS5 MATCH query processing, leading to a heap buffer overflow of attacker-controlled data in applications compiled with SQLITEENABLEFTS5.

Buffer Overflow vulnerability in SQLite affected version source snapshots/builds containing Fossil check-in 8bdc0d485e3ad0c7a1e818da66f106951d496b05cbe61d12c2c448f2f24b6d5d (Git mirror 169f68ed88b34cb68f720191c64c058f2ccec508, 2026-03-11) and later snapshots/builds allows an attacker to cause a denial of service via the ext/misc/sqlar.c, sqlarUncompressFunc(), sqlaruncompress(), sqlite3valueint64(), sqlite3malloc(int), uncompress() components

Accessibility. A logic issue was addressed with improved checks.

There exists a vulnerability in SQLite versions before 3.50.2 where the number of aggregate terms could exceed the number of columns available. This could lead to a memory corruption issue. We recommend upgrading to version 3.50.2 or above.

In SQLite before 3.32.3 select.c mishandles query-flattener optimization leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.

A flaw was found in SQLite's SELECT query functionality (src/select.c). This flaw allows an attacker who is capable of running SQL queries locally on the SQLite database to cause a denial of service or possible code execution by triggering a use-after-free. The highest threat from this vulnerability is to system availability.

ext/fts3/fts3snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo() query.

An issue in SQLite before Fossil check-in 869a51ae84df allows a local attacker to obtain sensitive information via the Session Extension changeset concat/changegroup merge path

An integer overflow in the sqlite3KeyInfoFromExprList function in SQLite versions 3.39.2 through 3.41.1 allows an attacker with the ability to execute arbitrary SQL statements to cause a denial of service or disclose sensitive information from process memory via a crafted SELECT statement with a large number of expressions in the ORDER BY clause.

In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and segmentation fault because of generated column optimizations.

ext/fts3/fts3.c in SQLite before 3.32.0 has a use-after-free in fts3EvalNextRow related to the snippet feature.

An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
