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: 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: 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.

CVE published 3 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed

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 3 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

Until a fix is available, users should consider disabling the plugin or restricting webhook endpoints to trusted sources to mitigate unauthorized payment confirmations.

Description

The Eupago Gateway for WooCommerce WordPress plugin versions 4.5.0 through 4.7.5 contains a vulnerability where it does not verify the authenticity of incoming payment-confirmation webhook requests in some configurations. This flaw allows unauthenticated attackers to forge payment confirmations and mark pending orders as paid without actual payment.

Impact

An attacker can forge payment confirmation webhook requests to the affected plugin versions, causing pending orders to be marked as paid without actual payment. This compromises the integrity of the order payment process and can lead to financial loss for merchants using the plugin. There is no reported impact on confidentiality or availability.

Summary

The vulnerability in the Eupago Gateway for WooCommerce WordPress plugin affects versions from 4.5.0 through 4.7.5. It arises because the plugin fails to authenticate incoming payment-confirmation webhook requests under certain configurations. As a result, attackers can send forged webhook requests to the plugin, causing it to mark orders as paid fraudulently. This can lead to financial loss due to unauthorized order fulfillment. The CVSS v3.1 base score is 5.3, indicating a medium severity level with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact is limited to integrity, with no confidentiality or availability impact reported.
