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 10 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

Upgrade the User Registration & Membership WordPress plugin to version 5.3.2 or later where this vulnerability is fixed. No other mitigation or workaround is indicated in the available data.

Description

A vulnerability in the User Registration & Membership WordPress plugin before version 5.3.2 allows unauthenticated users to exploit improperly validated discount coupons. This flaw permits users to obtain roles mapped to paid membership plans without payment, potentially escalating privileges up to administrator if the plan is linked to a privileged role.

Impact

Unauthenticated attackers can gain unauthorized roles, including potentially administrator privileges, without paying for the membership plan. This privilege escalation can compromise the integrity and security of the WordPress site by granting elevated access rights.

Summary

The User Registration & Membership WordPress plugin versions prior to 5.3.2 do not properly verify that a discount coupon applied to a paid membership plan is valid for that specific plan. This lack of validation allows unauthenticated users to submit fully discounted orders that are treated as paid, resulting in the assignment of the role associated with the paid plan. If the paid plan is mapped to a privileged role such as administrator, this can lead to privilege escalation.
