This includes operators, platform administrators, vulnerability management teams, and security teams who need to review and mitigate this vulnerability to prevent potential unauthorized page rendering and cache poisoning.

Why it matters

Defenders should care about CVE-2026-79713 because it affects the Breeze Cache WordPress plugin, potentially allowing unauthenticated attackers to manipulate page caching. This requires verification of the plugin version and updating to 2.5.15 or later if necessary. The impact is medium severity with a CVSS score of 6.5.

• Potential unauthorized page rendering under an attacker's request context.
• Possible cache poisoning and serving of malicious content to subsequent visitors.

Technical summary

The Breeze Cache WordPress plugin before 2.5.15 does not include a set of tracking-related query parameters in its page-cache key while still caching pages requested with them. This allows unauthenticated attackers to have a page rendered under their own request context stored under, and served from, the clean URL's cache entry to every subsequent visitor. The vulnerability has a medium severity with a CVSS score of 6.5. Defenders should prioritize verifying the plugin version and updating to 2.5.15 or later if necessary.
