Security readout for executives and security teams
Plain-English summary
CVE-2026-0745 affects the WordPress User Language Switch plugin through version 1.6.10. An administrator-level user could make the website server send requests to arbitrary locations, including internal services. The business risk is limited by the need for admin access, but it matters where WordPress can reach sensitive internal systems.
Executive priority
Treat as a moderate-priority WordPress plugin issue. Prioritize sites with many administrators, internet-facing admin panels, or network paths to internal services. It is less urgent than unauthenticated remote exploitation, but important if admin compromise is a realistic threat.
Technical view
The issue is server-side request forgery in User Language Switch, tied to missing URL validation in download_language() and the info_language parameter. The CVSS 3.1 score is 5.5 with PR:H and no user interaction. Sources describe possible querying or modifying internal services from the web application context.
Likely exposure
Exposure is limited to WordPress sites running User Language Switch versions up to and including 1.6.10, where an attacker already has Administrator-level access or higher.
Exploitation context
No CISA KEV listing or source-provided active exploitation evidence was included. The main plausible scenario is abuse by a compromised or malicious WordPress administrator account to reach systems accessible from the web server.
Researcher notes
The affected-version metadata in the bundle is not fully consistent, but the description and Wordfence reference state versions up to 1.6.10. Patch status is not clearly stated in the provided sources. Avoid assuming a fixed version unless confirmed by the plugin repository or vendor advisory.
Mitigation direction
- Inventory WordPress sites for the User Language Switch plugin and installed version.
- Check the WordPress plugin page and vendor guidance for an available fixed release.
- Update the plugin if a fixed version is available from trusted sources.
- Disable or remove the plugin where it is not required.
- Restrict administrator access and review admin accounts for compromise.
- Limit outbound network access from WordPress servers where feasible.
Validation and detection
- Confirm whether User Language Switch is installed and version is 1.6.10 or older.
- Review WordPress administrator accounts for unauthorized or unnecessary access.
- Check web server egress logs for unusual requests to internal addresses.
- Review plugin changelog or repository updates for URL validation changes.
- Verify network controls restrict WordPress from sensitive internal services.

Server-Side Request Forgery (SSRF)
Server-Side Request Forgery (SSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
