ImageMagick vulnerability
ImageMagick contains an unspecified vulnerability allowing server-side request forgery (SSRF) attacks via crafted images. The flaw has been exploited in the wild.
Verdict
Today item — known-exploited.
An attacker can craft a malicious image to trigger SSRF in ImageMagick, potentially accessing internal services, metadata, or resources not directly exposed to the internet. This vulnerability is actively exploited.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
1 independent public report of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2021-11-03).
Probability (EPSS)
EPSS 0.76897 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: ImageMagick, ImageMagick. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-20 Improper Input Validation.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a specially formatted image file designed to trigger image processing in the target application.
Business
The application processes user-supplied images without proper validation, creating an attack surface.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the SSRF flaw to make the server issue requests to internal network resources, cloud metadata endpoints, or localhost services.
Business
Internal systems and sensitive data become accessible to external attackers through the compromised image processing pipeline.
3
Lateral reach — past segmentation narrative 3
Attacker
I retrieve information about internal infrastructure, credentials, or service configurations exposed through the SSRF channel.
Business
Confidential operational details and authentication material are disclosed, enabling further compromise of the infrastructure.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
