ajv (Another JSON Schema Validator) before 8.18.0 is vulnerable to Regular Expression Denial of Service (ReDoS) when the $data option is enabled. The pattern keyword accepts runtime data via JSON Pointer syntax ($data reference), which is passed directly to the JavaScript RegExp() constructor without validation. An attacker can inject a malicious regex pattern (e.g., "^(a|a)*$") combined with crafted input to cause catastrophic backtracking. A 31-character payload causes approximately 44 seconds of CPU blocking, with each additional character doubling execution time. This enables complete denial of service with a single HTTP request against any API using ajv with $data: true for dynamic schema validation. This issue is also fixed in version 6.14.0.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-301cbbe347 advisory.

    This update contains upgrades to various npm packages used during the build to address CVEs, namely:

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - ajv (Another JSON Schema Validator) before 8.18.0 is vulnerable to Regular Expression Denial of Service
    (ReDoS) when the $data option is enabled. The pattern keyword accepts runtime data via JSON Pointer syntax
    ($data reference), which is passed directly to the JavaScript RegExp() constructor without validation. An
    attacker can inject a malicious regex pattern (e.g., "^(a|a)*$") combined with crafted input to cause

    fixed in version 6.14.0. (CVE-2025-69873)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
