This medium-severity CVE scores 5.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 99% 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).

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-26he, the -concatenate operation is missing policy checks, potentially resulting in both reading and writing to paths disallowed by the security policy. This issue has been fixed in version 7.1.2-26.
