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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.

AI-suggested

The only effective mitigation is to apply the vendor-provided update once it becomes available. As a partial mitigation before patching, restrict membership in the Certificate Manager Agents group to trusted users only, since exploitation requires an authenticated credential in that role. No other mitigations are currently available.

Description

CVE-2026-80110 is an authorization flaw in the pki-core component of Red Hat Enterprise Linux 10. The vulnerability arises from the v2 REST ACL filter using lexicographic string comparison instead of specificity to resolve permission conflicts, allowing a wildcard permission to override a more specific literal permission. This flaw permits an authenticated Certificate Manager Agent, a lower-privileged role, to perform administrative actions such as creating and activating arbitrary certificate-issuance profiles via the CA's profile-management REST API. The vulnerability impacts the confidentiality and integrity of the certificate authority's issuance policy.

Impact

An authenticated Certificate Manager Agent with lower privileges can perform administrative actions intended only for administrators, specifically creating and activating arbitrary certificate-issuance profiles. This compromises the integrity of the certificate authority's issuance policy and poses a confidentiality risk to relying parties trusting the issued certificates. The vulnerability does not affect availability and requires low privileges and no user interaction to exploit.

Summary

The vulnerability in pki-core's v2 REST ACL filter causes incorrect authorization by selecting tie-breaking permissions based on lexicographic string comparison rather than specificity. This results in a wildcard-mapped permission overriding a more specific literal-mapped permission when both match. Consequently, the POST /v2/profiles/raw endpoint, which should require Administrator-level profiles.create permission, can be accessed by users with the lower-privileged profiles.approve permission assigned to the default Certificate Manager Agents group. This allows an authenticated Certificate Manager Agent to author and activate arbitrary certificate-issuance profiles, compromising the integrity and confidentiality of the CA's issuance policy. The flaw requires an authenticated credential and does not allow unauthenticated remote code execution.
