CVE-2026-73635

Apache Struts (versions 2.0.0–2.3.37, 2.5.0–2.5.33, 6.0.0–6.10.0, 7.0.0–7.2.1) is vulnerable to unbounded localized-text cache growth: when no fixed locale is set, the request-supplied locale causes caches to expand without limit, exhausting the Java heap and causing denial of service. CVSS 7.5 (...
