GHSA-9fw2-h3hf-293r Spring Data Commons: Heap exhaustion from unbounded property-lookup cache retaining crafted string keys

• Maven org.springframework.data:spring-data-commons: >= 4.0.0, < 4.0.6 → fixed in 4.0.6 • Maven org.springframework.data:spring-data-commons: >= 3.5.0, < 3.5.12 → fixed in 3.5.12 • Maven org.springframework.data:spring-data-commons: >= 3.4.0, <= 3.4.14 (no fix yet) • Maven org.springframework.data:spring-data-commons: >= 3.3.0, <= 3.3.16 (no fix yet) • Maven org.springframework.data:spring-data-commons: <= 2.7.19 (no fix yet)

Spring Data's internal property-lookup cache accepts and permanently retains attacker-supplied strings as cache keys, allowing heap exhaustion through repeated requests. Affected versions: Spring Data Commons 2.7.0 through 2.7.19; 3.3.0 through 3.3.16; 3.4.0 through 3.4.14; 3.5.0 through 3.5.11; 4.0.0 through 4.0.5.
