CVE-2026-116067 ananthakumaran CVE debrief

Who should care

Defenders responsible for Paisa instances should assess exposure and apply patches to prevent exploitation. This includes verifying the version of Paisa being used, restricting access to the editor file and delete_backups endpoints, and monitoring for suspicious activity on Paisa instances. Additionally, defenders should review compensating controls for exposed systems while remediation is scheduled and verified, and track exceptions, retest remediated P

Why it matters

CVE-2026-116067 is a path traversal vulnerability in Paisa before version 0.7.8 that allows unauthenticated attackers to read files and delete backups. Defenders should prioritize verifying exposure and applying patches to prevent exploitation.

• Verify exposure of Paisa instances to path traversal attacks
• Assess potential for data theft or deletion through exploitation
• Prioritize patching of Paisa versions before 0.7.8
• Monitor for suspicious activity on Paisa instances

Technical summary

The vulnerability is caused by a path traversal issue in the GetFile, GetSheet, DeleteBackups, and DeleteSheetBackups handlers in Paisa before version 0.7.8. This allows unauthenticated attackers to read files and delete backups by sending crafted names to the editor file and delete_backups endpoints. The vulnerability has a high CVSS score of 8.8 and is considered HIGH severity. Defenders should prioritize verifying exposure and applying patches to prevent exploitation. The vulnerability was reported in Paisa before version 0.7.8 and allows unauthenticated attackers to read files and delete backups through path traversal.

Defensive priority

Defenders should prioritize verifying exposure and applying patches for Paisa versions before 0.7.8.

Recommended defensive actions

• Verify Paisa version and apply patch to 0.7.8 or later
• Restrict access to editor file and delete_backups endpoints
• Monitor for suspicious activity on Paisa instances
• 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
