Summary
Apache Cocoon vulnerable to Incorrect Usage of Seeds in Pseudo-Random Number Generator
Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) vulnerability in Apache Cocoon.
This issue affects Apache Cocoon: all versions.
When a continuation is created, it gets a random identifier. Because the random number generator used to generate these identifiers was seeded with the startup time, it may not have been sufficiently unpredictable, and an attacker could use this to guess continuation ids and look up continuations they should not have had access to.
As a mitigation, you may enable the "session-bound-continuations" option to make sure continuations are not shared across sessions.
As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.
NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- Which packages are affected by CVE-2025-24783?
org.apache.cocoon:cocoon-forms-impl(maven) (versions <= 2.3.0)org.apache.cocoon:cocoon-sitemap-impl(maven) (versions <= 2.3.0)
- Is there a fix for CVE-2025-24783? No fixed version is listed for CVE-2025-24783 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-24783 exploitable, and should I be worried? Whether CVE-2025-24783 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-24783 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
