CVE-2026-33981: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in dgtlmoon changedetection.io
changedetection.io is a free open source web page change detection tool. Prior to 0.54.7, the `jq:` and `jqraw:` include filter expressions allow use of the jq `env` builtin, which reads all process environment variables and stores them as the watch snapshot. An authenticated user (or unauthenticated user when no password is set, the default) can leak sensitive environment variables including `SALTED_PASS`, `PLAYWRIGHT_DRIVER_URL`, `HTTP_PROXY`, and any secrets passed as env vars to the container. Version 0.54.7 patches the issue.
AI Analysis
Technical Summary
The vulnerability in changedetection.io (CVE-2026-33981) arises from the use of jq's env builtin within jq: and jqraw: include filter expressions prior to version 0.54.7. This allows reading of all environment variables used by the process, potentially exposing sensitive data stored as environment variables. Access to this data requires authentication, but if no password is set (which is the default configuration), unauthenticated users can also exploit this. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and has a CVSS 4.0 score of 8.3, indicating high severity. The issue is resolved in version 0.54.7.
Potential Impact
Exploitation of this vulnerability can lead to unauthorized disclosure of sensitive environment variables, including passwords and secret URLs, which may compromise the security of the affected system or container. This exposure can facilitate further attacks or unauthorized access depending on the nature of the leaked secrets. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade changedetection.io to version 0.54.7 or later, where this vulnerability is patched. Until the upgrade is applied, ensure that a strong password is set to prevent unauthenticated access, as the default configuration allows unauthenticated users to exploit this issue. Patch status is confirmed by the vendor advisory indicating the fix in version 0.54.7.
