AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Local invocation bypasses path policy, enabling read (C:L) and write (I:L) to restricted paths; no availability impact described; PR:N as any local user can invoke ImageMagick.

Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Policy bypass in ImageMagick's -concatenate operation allows local users to read from and write to filesystem paths that the configured security policy explicitly prohibits. All versions prior to 7.1.2-26 are affected. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions: (1) ImageMagick prior to 7.1.2-26 is installed on the target system; (2) a security policy (policy.xml) is configured with path-based restrictions - environments without a configured policy have no guard to bypass and are not meaningfully affected by this specific flaw; (3) the attacker must be able to execute ImageMagick with the `-concatenate` option on the local system, either directly or indirectly via an application that exposes ImageMagick processing. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS 3.1 score of 5.5 (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) contains a notable internal inconsistency: the vector reports C:N and I:N (no confidentiality or integrity impact) yet the description explicitly states that both reading from and writing to disallowed paths are possible, and the assigned tags include 'Information Disclosure'. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with the ability to invoke ImageMagick on a shared system - such as a web application that calls ImageMagick to process user-uploaded images - passes a crafted `-concatenate` command that targets a path blocked by policy.xml, such as /etc/passwd or an application secrets directory. Because the policy check is missing, ImageMagick processes the request without error, returning file contents or writing attacker-controlled data to the restricted path. … |
| Remediation | Upgrade ImageMagick to version 7.1.2-26 or later, which introduces the missing policy checks for the `-concatenate` operation. … Detailed patch versions, workarounds, and compensating controls in full report. |
