Loco Translate: Cross-Site Request Forgery
CVE-2026-15005 is a high-severity cross-site request forgery vulnerability in Loco Translate from Timwhitlock, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Loco Translate versions: 2.8.5 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.33% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Loco Translate you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
The Loco Translate plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.8.5. This is due to missing or incorrect nonce validation on the execTemplate function. This makes it possible for unauthenticated attackers to execute arbitrary PHP code on the server by supplying a php://filter stream wrapper URI as the 'template' parameter, which bypasses path validation and is passed directly to the include sink in execTemplate() via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The underlying weakness: Cross-Site Request Forgery
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, use anti-CSRF packages such as the OWASP CSRFGuard. Another example is the ESAPI Session Management control, which includes a component for CSRF.
- Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
- Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
