SQL injection in ext-pgsql via E'...' backslash breakout

CVE-2026-17543GHSA-7qpv-r5mr-78m4

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (php 8.5.9, 8.4.24, 8.3.33, 8.2.33; libphp 8.5.9, 8.4.24, 8.3.33, 8.2.33; php-min 8.5.9, 8.4.24, 8.3.33, 8.2.33), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2026-17543

Advisory: SQL injection in ext-pgsql via E'...' backslash breakout
IDs: CVE-2026-17543, GHSA-7qpv-r5mr-78m4
Record: https://patchnext.com/advisories/cve-2026-17543 (revision 3, source checked 11 Nov 2026, 07:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: php 8.5.9, 8.4.24, 8.3.33, 8.2.33; libphp 8.5.9, 8.4.24, 8.3.33, 8.2.33; php-min 8.5.9, 8.4.24, 8.3.33, 8.2.33. A vendor fix does not mean a deployment is fixed.

## Affected components
- Bitnami php: affected >= 8.2.0, < 8.2.33; >= 8.3.0, < 8.3.33; >= 8.4.0, < 8.4.24; >= 8.5.0, < 8.5.9; fixed in 8.5.9, 8.3.33, 8.2.33, 8.4.24
- Bitnami libphp: affected >= 8.2.0, < 8.2.33; >= 8.3.0, < 8.3.33; >= 8.4.0, < 8.4.24; >= 8.5.0, < 8.5.9; fixed in 8.5.9, 8.3.33, 8.2.33, 8.4.24
- Bitnami php-min: affected >= 8.2.0, < 8.2.33; >= 8.3.0, < 8.3.33; >= 8.4.0, < 8.4.24; >= 8.5.0, < 8.5.9; fixed in 8.5.9, 8.3.33, 8.2.33, 8.4.24

## Suggested inspection (read-only)
- Bitnami php: check the installed version with your package manager.
- Bitnami libphp: check the installed version with your package manager.
- Bitnami php-min: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on php, libphp, php-min.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
