Spring Data web support unbounded negative-result cache keyed on attacker-supplied property names

HIGH | JUNE 09, 2026 | CVE-2026-41716

Description

Spring Data's internal property-lookup cache accepts and permanently retains attacker-supplied strings as cache keys, allowing heap exhaustion through repeated requests.

Affected applications are those using Spring Data features that forward HTTP-supplied strings to PropertyPath.from without prior filtering, in particular Querydsl web bindings (via QuerydslPredicateArgumentResolver) with the default permit-all visibility, and @ProjectedPayload form-parameter binding (via MapDataBinder).
