CyberRota Analysis
AI-GeneratedThe vulnerability allows unauthenticated attackers to manipulate the fav_count of any echo by exploiting the PUT /api/echo/like/:id endpoint, which is accessible without authentication or rate limiting. This can lead to inflated popularity metrics and increased load on the database and cache due to repeated requests. Organizations using affected versions prior to 4.7.3 should prioritize patching to mitigate potential abuse and performance degradation.

Original NVD Description
Ech0 through 4.5.6 registers the PUT /api/echo/like/:id endpoint on the public router group without authentication or rate limiting. Unauthenticated attackers can increment the fav_count counter of any echo (including private echoes) by supplying its UUID, which can be harvested from the public GET /api/echo/page feed. Repeated requests are accepted without deduplication, each triggering a database write and a four-key cache invalidation, allowing attackers to inflate popularity metrics and amplify load on the database and cache. Fixed in 4.7.3.
