CVE-2026-50813

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

CVE-2026-50812

A NULL pointer dereference in the SQLite Session Extension in SQLite 3.53.1 and SQLite trunk builds before check-in e807d4e3798efd53 allows an attacker who can supply a malformed changeset blob to cause a denial of service. The issue occurs when sqlite3changeset_apply_v3() applies a corrupt changeset and reaches sqlite3_value_type() with a NULL sqlite3_value pointer.

SQLite before 3.53.2 Heap Buffer Overflow via FTS5 fts5ChunkIterate

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 SQLITE_ENABLE_FTS5.

SQLite before 3.53.2 Memory Corruption in FTS5 Extension

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.

Integer Truncation on SQLite

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.

CVE-2025-29088

In SQLite 3.49.0 before 3.49.1, certain argument values to sqlite3_db_config (in the C-language API) can cause a denial of service (application crash). An sz*nBig multiplication is not cast to a 64-bit integer, and consequently some memory allocations may be incorrect.

CVE-2020-35527

In SQLite 3.31.1, there is an out of bounds access problem through ALTER TABLE for views that have a nested FROM clause.

CVE-2020-35525

In SQlite 3.31.1, a potential null pointer derreference was found in the INTERSEC query processing.

CVE-2022-35737

SQLite 1.0.12 through 3.39.x before 3.39.2 sometimes allows an array-bounds overflow if billions of bytes are used in a string argument to a C API.

CVE-2020-13631

SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c.

CVE-2019-19926

multiSelect in select.c in SQLite 3.30.1 mishandles certain errors during parsing, as demonstrated by errors from sqlite3WindowRewrite() calls. NOTE: this vulnerability exists because of an incomplete fix for CVE-2019-19880.
