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: 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: 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.

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

Until an official fix is available, administrators should consider restricting access to the plugin's AJAX handlers, implementing custom nonce and capability checks if possible, or disabling the plugin if feasible. Monitoring for suspicious user activity related to data deletion may help detect exploitation attempts.

Description

The tholstkabelbwde WordPress plugin 'CMS für Motorrad Werkstätten' versions up to 1.0.0 contains a Cross-Site Request Forgery (CSRF) vulnerability. This arises from missing nonce validation and lack of capability checks on eight AJAX deletion handlers. An attacker can exploit this by tricking a logged-in user into submitting a malicious request, potentially causing deletion of various data such as vehicles, contacts, suppliers, receipts, positions, catalog articles, stock items, or entire supplier catalogs. The vulnerability has a CVSS score of 4.3, indicating medium severity. No official patch or remediation guidance is currently available, and no known exploits are reported in the wild.

Impact

Successful exploitation can lead to unauthorized deletion of various data types within the plugin, including vehicles, contacts, suppliers, receipts, positions, catalog articles, stock items, and supplier catalogs. This results in integrity loss of the affected data but does not impact confidentiality or availability. The attack requires a logged-in user to be tricked into performing an action, such as clicking a malicious link, and does not require attacker privileges.

Summary

CVE-2026-6451 is a CSRF vulnerability in the tholstkabelbwde WordPress plugin 'CMS für Motorrad Werkstätten' affecting versions up to 1.0.0. The issue stems from the absence of nonce validation (no calls to check_ajax_referer() or wp_verify_nonce()) and missing capability checks (no current_user_can() calls) in eight AJAX deletion handlers. This allows attackers to craft forged requests that, when executed by an authenticated user, can delete critical data entities managed by the plugin. The vulnerability is classified under CWE-352 and has a CVSS 3.1 base score of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N), reflecting a network attack vector with low complexity and requiring user interaction but no privileges.

Compound weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #3OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Architecture and Design
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
