Integrity: Low
Availability: None

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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Nov 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

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 6 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 PublishPress Revisions (WordPress plugin) to 4.3.1.

AI-suggested

Upgrade PublishPress Revisions to version 4.3.1 or later, where this missing authorization vulnerability has been fixed. No other mitigation is required as the issue is resolved by this official patch.

Description

CVE-2026-120851 is a Missing Authorization vulnerability in the PublishPress Revisions plugin up to version 4.2.0. It allows exploitation due to incorrectly configured access control security levels, potentially enabling unauthorized users with limited privileges to perform actions they should not be allowed to. The issue is fixed in version 4.3.1.

Impact

Exploitation of this vulnerability could allow an attacker with limited privileges to perform unauthorized actions within the PublishPress Revisions plugin, potentially modifying revision data. The impact is limited to integrity loss without affecting confidentiality or availability. There are no known exploits in the wild.

Summary

This vulnerability in PublishPress Revisions involves missing authorization checks that allow users with limited privileges to exploit incorrectly configured access control mechanisms. The flaw affects all versions from initial releases up to 4.2.0. The vulnerability has a CVSS 3.1 base score of 4.3 (medium severity), indicating a network attack vector with low complexity and no user interaction required, but limited impact confined to integrity loss without confidentiality or availability impact. The issue is resolved in version 4.3.1.
