PostgreSQL reindexdb index name quoting allows SQL injection

Assigner: PostgreSQL
Reserved: 26.10.2026 Published: 12.11.2026 Updated: 12.11.2026

SQL injection in PostgreSQL reindexdb allows an object creator to execute arbitrary SQL as the database user running reindexdb, via a crafted index name embedded in the parallel catalog query for --jobs with --index. Within major versions 17-18, minor versions before PostgreSQL 18.7 and 17.12 are affected. Versions before PostgreSQL 17 are unaffected.
