CVE-2026-54619 sparklemotion CVE debrief

A use-after-free vulnerability exists in sqlite3-ruby version 2.9.4 and earlier. The issue arises when redefining a SQLite function with a different arity, which frees the previously registered function handler while SQLite may still reference it. This vulnerability is fixed in version 2.9.5. The vulnerability could lead to crashes or unexpected behavior if exploited. Developers should verify exposure, especially in applications with custom SQLite functions, and consider upgrading to version 2.9.5 or later.

Who should care

Ruby developers and security teams using sqlite3-ruby, especially those defining custom SQLite functions, should assess potential exposure and verify their current version. This includes reviewing the current version of sqlite3-ruby in use, checking for custom SQLite functions, and considering an upgrade to version 2.9.5 or later if necessary. Security teams should also review compensating controls and monitor for potential exploitation.

Why it matters

A use-after-free vulnerability in sqlite3-ruby could lead to crashes or unexpected behavior if exploited. Defenders should verify exposure, especially in applications with custom SQLite functions, and consider upgrading to version 2.9.5 or later.

  • Verification of exposure in Ruby applications using sqlite3-ruby is necessary.
  • Potential for crashes or unexpected behavior if the vulnerability is exploited.
  • Upgrading to version 2.9.5 or later may be necessary to mitigate the issue.
  • Further investigation is required to determine the full scope of potential impact.

Technical summary

The sqlite3-ruby library provides Ruby bindings for the SQLite3 embedded database. In version 2.9.4 and earlier, a use-after-free vulnerability occurs when redefining a SQLite function with a different arity. This frees the previously registered function handler while SQLite may still reference it. The issue is addressed in version 2.9.5. The vulnerability could lead to crashes or unexpected behavior if exploited. Defenders should prioritize verifying exposure in Ruby applications using sqlite3-ruby, especially those with custom SQLite functions.

Defensive priority

Defenders should prioritize verifying exposure in Ruby applications using sqlite3-ruby, especially those with custom SQLite functions. Immediate action is not critical due to the low CVSS score, but upgrading to version 2.9.5 or later is recommended.

Recommended defensive actions

  • Verify if the current version of sqlite3-ruby is being used in the environment.
  • Check if custom SQLite functions are defined and assess potential exposure.
  • Upgrade to sqlite3-ruby version 2.9.5 or later if possible.
  • Review compensating controls for exposed systems while remediation is scheduled and verified.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability. The sqlite3-ruby GitHub repository contains details about the fix in version 2.9.5. However, specific details about exploitation or impact are not provided.
