{"affected":[{"product":"chartbrew","source":"CNA: GitHub_M","vendor":"chartbrew","versions":[{"status":"affected","version":"< 5.2.3"}]}],"cveId":"CVE-2026-85736","cwes":["CWE-73"],"description":"Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.3, connection creation or update stored attacker-chosen absolute SSL and SSH file paths, and later connection cleanup passed those stored paths to fs.unlink without a path restriction. The vulnerable surface is data-connection certificate and SSH-key cleanup when a connection is removed. A user with createOwn and deleteOwn permissions on their own team stores a target path in a connection and then deletes the connection to trigger cleanup; default self-signup grants teamOwner these permissions. The cleanup routine treats the stored SSL or SSH path as a managed certificate path and unlinks the referenced file; duplicateConnection provides a second advisory-identified trigger. The attacker must be able to create or update and then delete a connection on their own team. The default container runs Chartbrew as uid 0, while deployments with a less-privileged process are limited by that process's deletion permissions. The attacker can delete files such as /code/.env or application source, causing integrity loss and service disruption. This issue is fixed in version 5.2.3.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.1,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"}],"modifiedAt":1793999342969,"publishedAt":1793999342969,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/chartbrew/chartbrew/security/advisories/GHSA-p5h6-f969-jpfv"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/chartbrew/chartbrew/commit/aa931cc868eff8c4343ae2263539fa2d0d4a0943"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/chartbrew/chartbrew/releases/tag/v5.2.3"}],"remediation":[],"revision":"5c53cb0281265e3e3314498f930f2d5c0c3cfb7d1e624fe01a0f2760ab76e44c","sources":[{"modifiedAt":1793999342969,"name":"CNA: GitHub_M","retrievedAt":1794002947488,"url":"https://www.cve.org/CVERecord?id=CVE-2026-85736"}],"ssvc":null,"status":"published","title":"Chartbrew: Arbitrary file deletion as root via data connection SSL/SSH paths","updatedAt":1794002947488}
