CVE-2026-59282

CVE-2026-59282 is a denial-of-service flaw in Spring Framework's data binding infrastructure, which applications use to apply user-supplied property paths onto target objects. An unauthenticated remote attacker can trigger it by sending crafted property paths to any application that binds user-controlled paths onto objects, causing uncontrolled resource consumption (CWE-400). The attacker gains the ability to exhaust resources and disrupt service availability; confidentiality and integrity are not impacted, consistent with the CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Effectively every maintained Spring Framework line is affected, from 5.2.25.RELEASE and earlier through 7.0.8, so any Spring-based application that exposes user-controlled property paths to its binding layer is in scope. Exploitation status is currently quiet: no public proof of concept is known, the CVE is not in CISA KEV, and EPSS assigns only a 0.3% probability of exploitation within 30 days (25th percentile).

What to do: Upgrade each deployment to a patched Spring Framework release beyond the affected ceilings in its branch (newer than 7.0.8, 6.2.19, 6.1.28, 6.0.30, 5.3.49, and 5.2.25.RELEASE). Until patched, audit network-facing endpoints that allow users to supply property paths for data binding and restrict or validate those paths to limit resource consumption. Applications that never expose user-controlled property paths to the binding infrastructure are not considered affected.
