EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 64% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Wekan is open source kanban built with Meteor. Prior to 9.75, models/fileValidation.js interpolated the uploaded fileObj.path into the administrator-configured externalCommandLine at its {file} placeholder and executed the result through asyncExec, which is promisify(exec) and invokes /bin/sh -c. On deployments with an external scanner configured, an authenticated user able to upload an attachment could place shell metacharacters such as command substitutions in the filename and execute commands as the Wekan server process. Version 9.75 adds shellQuote() and passes the file path as a POSIX single-quoted argument so shell metacharacters cannot escape the placeholder. This issue is fixed in version 9.75.
