Detectable: no evidence on record.

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 5 Nov 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.

What to do

Upgrade Red Hat gegl04 to 9.4.1.

ZDI-26-282: GIMP HDR File Parsing Heap-based Buffer Overflow Remote Code Execution VulnerabilityZero Day Initiative2026-04-15

Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on affected systems via specially crafted HDR files processed by GIMP. This could lead to full compromise of the affected system. Red Hat rates the security impact as Important (high severity). No known exploits in the wild have been reported at this time.

Summary

The vulnerability CVE-2026-2050 affects the GEGL (Generic Graphics Library) component used by GIMP. It is a heap-based buffer overflow in the HDR file parsing code that could lead to arbitrary code execution. Red Hat has released a security advisory (RHSA-2026:56964) providing updated packages for Red Hat Enterprise Linux 9.4 and its variants to fix this issue. The advisory references the CVE for detailed impact and scoring information. No public exploit or CVSS score is currently provided in the data. The fix is available via updated gegl04 packages as detailed in the Red Hat advisory.

CWE-131Incorrect Calculation of Buffer Size (opens in a new tab)
Base weaknessLikelihood of exploit: High
The product does not correctly calculate the size to be used when allocating a buffer.
Implementation
When allocating a buffer for the purpose of transforming, converting, or encoding an input, allocate enough memory to handle the largest possible encoding. For example, in a routine that converts "&" characters to "&" for HTML entity encoding, the output buffer needs to be at least 5 times as large as the input…
Implementation
Understand the programming language's underlying representation and how it interacts with numeric calculation (CWE-681). Pay close attention to byte size discrepancies, precision, signed/unsigned distinctions, truncation, conversion and casting between types, "not-a-number" calculations, and how the language handles…
Implementation · Input Validation
Perform input validation on any numeric input by ensuring that it is within the expected range. Enforce that the input meets both the minimum and maximum requirements for the expected range.
