How severe is CVE-2025-35036?

No CVSS score has been assigned to CVE-2025-35036 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-35036?

CVE-2025-35036 affects the following packages: org.hibernate.validator:hibernate-validator (Maven), org.hibernate.validator:hibernate-validator (Maven), org.hibernate:hibernate-validator (Maven), org.hibernate:hibernate-validator (Maven). Ecosystems affected: Maven.

How do I fix CVE-2025-35036?

Update org.hibernate.validator:hibernate-validator to 6.2.0.CR1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-35036 is resolved across your whole dependency graph.

How do I detect CVE-2025-35036 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.hibernate.validator:hibernate-validator, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-35036 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2025-35036 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-35036 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-2025-35036?

CVE-2025-35036 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 56th 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-2025-35036?

CVE-2025-35036 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2025-35036 published, and has it been updated?

CVE-2025-35036 was published on June 3, 2025 and was last updated on October 28, 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

Hibernate Validator before 6.2.0 and 7.0.0, by default and depending how it is used, may interpolate user-supplied input in a constraint violation message with Expression Language. This could allow an attacker to access sensitive information or execute arbitrary Java code. Hibernate Validator as of 6.2.0 and 7.0.0 no longer interpolates custom constraint violation messages with Expression Language and strongly recommends not allowing user-supplied input in constraint violation messages. CVE-2020-5245 and CVE-2025-4428 are examples of related, downstream vulnerabilities involving Expression Language intepolation of user-supplied data.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatImportant

This vulnerability marked as Important rather than Moderate because it enables Expression Language (EL) injection through user-supplied input embedded in validation messages — effectively escalating a benign validation failure into a potential Remote Code Execution (RCE) vector. In environments where EL expressions…

Workaround published by Red Hat

Users who are unable to upgrade should manually disable Expression Language interpolation to prevent EL injection. If disabling is not feasible, carefully sanitize and validate any dynamic input before inclusion.
