Heap Exhaustion DoS in Spring Data Commons Property Lookup Cache
CVE-2026-41716 is a high-severity denial-of-service vulnerability in Spring Data web support, rooted in Spring Data Commons. Spring Data's internal property-lookup cache accepts attacker-controlled property-name strings as cache keys and permanently retains negative lookup results, creating an unbounded cache growth condition. When applications pass unfiltered HTTP-supplied property names into property path resolution, including via PropertyPath.from, an attacker can send repeated requests containing unique malicious property-name strings and force continuous heap consumption. Documented exposed paths include Querydsl web bindings through QuerydslPredicateArgumentResolver, particularly with default permit-all visibility, and @ProjectedPayload form-parameter binding through MapDataBinder. The issue affects 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, and 4.0.0 through 4.0.5; unsupported versions are also reported as affected transitively through Spring Data Commons.
