CVE-2026-54715 allinurl CVE debrief

Who should care

GoAccess users, particularly those using version 1.10.2, should be aware of this vulnerability and take steps to upgrade or mitigate the risk. Users should confirm whether affected product deployments exist in managed environments and assign an owner for follow-up. Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. 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. Prioritize upgrading to version 1.11 to address the heap corruption vulnerability. Review compensating controls for exposed systems while remediation is scheduled and verified. Implement additional monitoring for suspicious User-Agent strings. Asset inventory and security teams should review their systems for potential exposure and plan accordingly. Vulnerability management teams should assess the risk and prioritize remediation efforts. Operators of affected systems should take immediate action to protect their environments. Security teams should review their incident response plans and be prepared to respond to potential exploitation attempts. Rollback/change windows and source tracking should be considered for exposed systems. Compensating controls and monitoring should be implemented for systems that cannot be immediately patched. A thorough review of system logs and monitoring data is recommended to detect potential exploitation attempts. Additionally, users should consider implementing asset inventory management to track affected systems and prioritize remediation efforts. Source tracking and monitoring can help identify potential security threats and improve incident response. By taking these steps, users can help protect their systems from potential exploitation and minimize the risk of heap corruption or crashes. It is essential to stay informed about the vulnerability and take proactive measures to prevent exploitation. Users should also review their security policies and procedures to ensure они

Technical summary

The parse_browser function in GoAccess version 1.10.2 improperly handles crafted User-Agent strings, allowing an attacker to write one to four attacker-influenced bytes beyond the heap allocation. This can lead to heap corruption or crashes. The issue is addressed in GoAccess version 1.11. Affected GoAccess users should prioritize upgrading to version 1.11 to address the heap corruption vulnerability. Review access logs for potential exploitation attempts and implement additional monitoring for suspicious User-Agent strings.

Defensive priority

GoAccess users should prioritize upgrading to version 1.11 to address the heap corruption vulnerability.

Recommended defensive actions

• Upgrade GoAccess to version 1.11 or later
• Review access logs for potential exploitation attempts
• Implement additional monitoring for suspicious User-Agent strings
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record indicates that GoAccess version 1.10.2 is vulnerable to a heap corruption issue due to improper parsing of the User-Agent string in the parse_browser function. The issue is fixed in version 1.11. However, the exact scope of affected systems and potential attack vectors are not detailed in the provided source corpus. Users should verify their deployments and review compensating controls for exposed systems while remediation is scheduled and verified.
