Exploitation evidence

Disclosed: evidence found.
CVE published 6 Apr 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 30 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat has released security updates for ImageMagick in Red Hat Enterprise Linux 7 Extended Lifecycle Support to address these vulnerabilities. Users should apply the updates provided in advisory RHSA-2026:6713 following Red Hat's official guidance at https://access.redhat.com/articles/11258. No alternative mitigations or workarounds are specified. Patch status is confirmed as fixed in the updated packages.

Description

ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats. Security Fix(es): * ImageMagick: ImageMagick: Out-of-bounds read or write due to integer overflow in DIB coder (CVE-2026-28693) * ImageMagick: ImageMagick: Denial of Service via uninitialized pointer dereference in JBIG decoder (CVE-2026-28691) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

The integer overflow in the DIB coder may allow out-of-bounds memory access, potentially leading to memory corruption. The uninitialized pointer dereference in the JBIG decoder can cause denial of service by crashing the application. Both vulnerabilities affect the stability and security of systems processing maliciously crafted image files with ImageMagick.

Summary

ImageMagick versions included in Red Hat Enterprise Linux 7 Extended Lifecycle Support contain two vulnerabilities: CVE-2026-28693, an out-of-bounds read or write due to integer overflow in the DIB coder, and CVE-2026-28691, a denial of service vulnerability caused by uninitialized pointer dereference in the JBIG decoder. These issues could lead to memory corruption or service disruption. Red Hat has released updated packages to remediate these vulnerabilities as detailed in advisory RHSA-2026:6713.

CWE-824Access of Uninitialized Pointer (opens in a new tab)
Base weakness
The product accesses or uses a pointer that has not been initialized.

From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
