**Notable changes in this release include:**

## Features

- Allow the Docker container image to run as a non-default user via the `PUID` and `PGID` environment variables.

## Bugs/Housekeeping

- Fix cross-user data access and shared-server privilege escalation in server mode (**CVE-2026-7813**).
- Tighten Shared Server feature parity, owner-only field handling, and write guards as a follow-up to the data-isolation hardening.
- Fix stored cross-site scripting (XSS) via crafted PostgreSQL object names rendered in the Browser Tree and Explain Visualizer (**CVE-2026-7814**).
- Fix SQL injection in the Maintenance tool option values (**CVE-2026-7815**).
- Fix OS command injection in Import/Export query export (**CVE-2026-7816**).
- Fix local-file inclusion and server-side request forgery in the LLM API configuration endpoints (**CVE-2026-7817**).
- Fix unsafe deserialization in the session manager that could lead to remote code execution (**CVE-2026-7818**). This change also encrypts session files at rest using Fernet, restricts session-file and `DATA_DIR` permissions to `0o600`, switches the session-digest default from SHA-1 to SHA-256, and drops several non-roundtrippable live objects from the session.
- Fix symlink-based path traversal in the file manager (**CVE-2026-7819**).
- Fix account-lockout bypass on Flask-Security's default `/login` view so the `locked` field is honored on every authentication path (**CVE-2026-7820**).
- Use absolute paths for `a2enmod` and `a2enconf` in the Debian setup script so it works when `/usr/sbin` is not on `PATH`.
- Bump Python and JavaScript runtime/development dependencies, and upgrade ESLint to v10.
- Update the Czech, Italian, Russian, Spanish, and Swedish translations.

## Deprecations

- The **BigAnimal** cloud deployment integration is deprecated and will be removed in the next version of pgAdmin 4.
