CVE-2025-41249 has a CVSS score of 7.5/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2025-41249?

CVE-2025-41249 affects the following packages: org.springframework:spring-core (Maven), org.springframework:spring-core (Maven), org.springframework:spring-core (Maven). Ecosystems affected: Maven.

How do I fix CVE-2025-41249?

No patched version of org.springframework:spring-core has shipped for CVE-2025-41249 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

How do I detect CVE-2025-41249 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework:spring-core. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2025-41249 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2025-41249?

O3 pinpoints whether CVE-2025-41249 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-41249 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-41249 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-41249?

CVE-2025-41249 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 36th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-41249?

CVE-2025-41249 is classified as CWE-285 (CWE-285). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2025-41249 published, and has it been updated?

CVE-2025-41249 was published on September 16, 2025 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

The Spring Framework annotation detection mechanism may not correctly resolve annotations on methods within type hierarchies with a parameterized super type with unbounded generics. This can be an issue if such annotations are used for authorization decisions.

Your application may be affected by this if you are using Spring Security's @EnableMethodSecurity feature.

You are not affected by this if you are not using @EnableMethodSecurity or if you do not use security annotations on methods in generic superclasses or generic interfaces.

This CVE is published in conjunction with CVE-2025-41248 https://spring.io/security/cve-2025-41248 .
