Scope: Unchanged
Confidentiality: None
Integrity: None
Availability: High

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Mar 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

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 29 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

To mitigate CVE-2026-31793, organizations should promptly update iccDEV to version 2.3.1.5 or later, where the vulnerability is fixed. For environments where immediate patching is not feasible, restrict local access to systems processing ICC profiles and limit user permissions to reduce the risk of exploitation. Implement input validation and sanitization for ICC profiles before processing to detect and block malformed or suspicious files. Employ application-level monitoring to detect crashes or abnormal behavior in services using iccDEV, enabling rapid incident response. Additionally, educate users about the risks of opening untrusted ICC profiles or files that may trigger the vulnerability. For high-security environments, consider sandboxing or isolating applications handling ICC profiles to contain potential denial of service impacts. Regularly review and update security policies to include vulnerability management for third-party libraries like iccDEV.

Description

CVE-2026-31793 is an out-of-bounds read vulnerability in the InternationalColorConsortium's iccDEV library versions prior to 2.3.1.5. The flaw occurs in the CIccCalculatorFunc::ApplySequence() function, where an invalid or wild pointer read can cause a segmentation fault, leading to denial of service. Exploitation requires local access and user interaction, but no privileges are needed. The vulnerability impacts availability without affecting confidentiality or integrity. No known exploits are currently reported in the wild. The issue is fixed in version 2.3.

Impact

The primary impact of CVE-2026-31793 is denial of service due to application crashes when processing malicious or malformed ICC color profiles. Organizations that rely on iccDEV for color management in imaging, printing, or graphics workflows may experience service disruptions, affecting operational continuity. While the vulnerability does not compromise data confidentiality or integrity, the availability impact can interrupt automated workflows, degrade user experience, or halt critical imaging processes. This could be particularly problematic in industries such as digital publishing, printing services, and multimedia production where color profile handling is integral. The requirement for local access and user interaction limits remote exploitation, reducing the risk of widespread automated attacks. However, insider threats or compromised user accounts could leverage this vulnerability to disrupt services. No known active exploits reduce immediate risk, but unpatched systems remain vulnerable to targeted denial of service attempts.
