CVE-2026-90773 dalance CVE debrief

Who should care

Defenders and system administrators responsible for systems using procs should assess exposure and prioritize verification and updates. This includes reviewing and updating incident response plans, conducting regular vulnerability assessments, and implementing compensating controls to restrict terminal access. Additionally, security teams should implement monitoring and detection controls to identify potential exploitation and develop a patch management过程.

Why it matters

procs through 0.14.12 is vulnerable to terminal escape sequence injection via command lines, allowing local attackers to execute malicious processes, which defenders should prioritize verifying and updating, and monitoring for suspicious process executions.

• Defenders must verify and update procs to prevent terminal escape sequence injection
• System administrators must monitor for suspicious process executions to detect potential attacks
• Security teams must implement compensating controls to restrict terminal access and prevent exploitation

Technical summary

procs through 0.14.12 fails to sanitize escape sequences in process command lines before displaying them in the Command column, allowing local attackers to execute processes with malicious ANSI or OSC escape sequences. This vulnerability enables potential terminal escape sequence injection, allowing local attackers to execute malicious processes. The affected product, procs, fails to properly sanitize user input, allowing for potential exploitation. Defenders should prioritize verifying and updating procs to a version that sanitizes escape sequences in command lines.

Defensive priority

Defenders should prioritize verifying and updating procs to a version that sanitizes escape sequences in command lines, and monitor for suspicious process executions.

Recommended defensive actions

• Verify and update procs to a version that sanitizes escape sequences in command lines
• Monitor for suspicious process executions
• Implement compensating controls to restrict terminal access
• Review and update incident response plans to address potential exploitation
• Conduct regular vulnerability assessments to identify potential exposures
• Develop and implement a patch management process to ensure timely updates
• Verify and document the effectiveness of implemented controls

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but the scope of affected versions and systems requires verification from the supplied official sources. To verify, defenders should review the official CVE record and NVD entry for accuracy and check for any additional information from the vendor or other reliable sources. This includes confirming the affected versions, systems, and potential impact on the organization. Additionally, defenders should assess their exposure and prioritize verification and updates.
