GHSA-mqvw-jfmh-93qq

MEDIUM

GHSA-mqvw-jfmh-93qq is a medium-severity (CVSS 5) vulnerability in org.springframework.boot:spring-boot-cassandra. O3 Security confirms whether GHSA-mqvw-jfmh-93qq is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

Spring Boot's Cassandra auto-configuration does not perform hostname verification when establishing an SSL connection to Cassandra.

Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); Cassandra SSL auto-configuration. Versions that are no longer supported are also affected per vendor advisory.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.boot:spring-boot-cassandra. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update org.springframework.boot:spring-boot-cassandra to 4.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mqvw-jfmh-93qq is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-mqvw-jfmh-93qq is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-mqvw-jfmh-93qq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
