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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 14 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

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 2026-10-25.

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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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

European organizations should immediately verify the version of the QSM plugin installed on their WordPress sites and upgrade to version 10.2.3 or later where the CSRF protection is implemented. If you cannot patch yet, administrators should be advised to avoid clicking on suspicious links or visiting untrusted websites while logged into WordPress admin accounts to reduce the risk of CSRF exploitation. Implementing additional security controls such as Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide a temporary safeguard. Organizations should also enforce strict session management policies, including short session timeouts and multi-factor authentication (MFA) for admin accounts, to limit the window of opportunity for attackers. Regular security awareness training focused on phishing and social engineering can help reduce the likelihood of an admin falling victim to CSRF attack vectors. Finally, monitoring and logging changes to plugin settings can help detect unauthorized modifications early, enabling rapid incident response.

Description

The Quiz and Survey Master (QSM) WordPress plugin before 10.2.3 does not have CSRF check in place when updating its settings, which could allow attackers to make a logged in admin change them via a CSRF attack.

Impact

For European organizations using WordPress sites with the QSM plugin, this vulnerability poses a significant risk to the integrity and availability of their web-based quiz and survey functionalities. An attacker exploiting this flaw could alter plugin settings to disrupt normal operations, potentially leading to data loss or corruption of survey results, which may affect decision-making processes reliant on this data. Additionally, unauthorized configuration changes could be leveraged to inject malicious scripts or redirect users, thereby compromising confidentiality and potentially facilitating further attacks such as phishing or malware distribution. Since the attack requires an authenticated admin session, the impact is limited to organizations where administrators may be tricked into visiting malicious sites, highlighting the importance of user awareness. However, the ease of exploitation through social engineering and the high privileges of admin accounts amplify the threat. For organizations in sectors like education, market research, or any domain relying on survey data integrity, this vulnerability could undermine trust and operational continuity. Moreover, if exploited at scale, it could lead to reputational damage and regulatory scrutiny under European data protection laws such as GDPR, especially if personal data collected via surveys is compromised or manipulated.

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).
