EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 1.1%, top 36% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Soko if the code that powers packages.gentoo.org. Prior to version 1.0.2, the two package search handlers, Search and SearchFeed, implemented in pkg/app/handler/packages/search.go, are affected by a SQL injection via the q parameter. As a result, unauthenticated attackers can execute arbitrary SQL queries on https://packages.gentoo.org/. It was also demonstrated that primitive was enough to gain code execution in the context of the PostgreSQL container. The issue was addressed in commit 4fa6e4b619c0362728955b6ec56eab0e0cbf1e23y of version 1.0.2 using prepared statements to interpolate user-controlled data in SQL queries.
