How severe is CVE-2025-53623?

No CVSS score has been assigned to CVE-2025-53623 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-53623?

CVE-2025-53623 affects the following packages: job-iteration (RubyGems). Ecosystems affected: RubyGems.

How do I fix CVE-2025-53623?

Update job-iteration to 1.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53623 is resolved across your whole dependency graph.

How do I detect CVE-2025-53623 in my RubyGems dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for job-iteration. 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-2025-53623 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-2025-53623?

O3 pinpoints whether CVE-2025-53623 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-2025-53623 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-53623 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-2025-53623?

CVE-2025-53623 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 48th 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.

When was CVE-2025-53623 published, and has it been updated?

CVE-2025-53623 was published on July 14, 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.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.

Description

The Job Iteration API is an an extension for ActiveJob that make jobs interruptible and resumable Versions prior to 1.11.0 have an arbitrary code execution vulnerability in the CsvEnumerator class. This vulnerability can be exploited by an attacker to execute arbitrary commands on the system where the application is running, potentially leading to unauthorized access, data leakage, or complete system compromise. The issue is fixed in versions 1.11.0 and above. Users can mitigate the risk by avoiding the use of untrusted input in the CsvEnumerator class and ensuring that any file paths are properly sanitized and validated before being passed to the class methods. Users should avoid using the count_of_rows_in_file method with untrusted CSV filenames.
