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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to 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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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

Monitor for and apply official patches or updates from Tendenci CMS as soon as they become available to address CVE-2025-70959.
Implement strict input validation and output encoding on all user-supplied data in the Jobs module to prevent injection of malicious scripts.
Restrict user privileges to the minimum necessary, especially limiting who can post or edit job listings to reduce the attack surface.
Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context.
Conduct regular security audits and penetration testing focused on web application vulnerabilities, including XSS.
Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content within the CMS.
Use web application firewalls (WAF) with rules tuned to detect and block XSS payloads targeting the Jobs module.
Review and sanitize existing job postings to remove any potentially malicious content that may have been injected prior to mitigation.

Description

CVE-2025-70959 is a stored cross-site scripting (XSS) vulnerability found in the Jobs module of Tendenci CMS version 15.3.7. This vulnerability allows an attacker with limited privileges and requiring user interaction to inject malicious scripts or HTML, which execute in the context of other users' browsers. The vulnerability impacts confidentiality and integrity but does not affect availability. Exploitation requires authentication and user interaction, limiting its ease of exploitation. No known exploits are currently reported in the wild. European organizations using Tendenci CMS for job postings or recruitment portals should be aware of this risk. Mitigation involves applying patches once available, sanitizing inputs, and restricting user privileges. Countries with higher Tendenci CMS adoption and significant online recruitment activities are more likely to be affected.

Impact

For European organizations using Tendenci CMS, especially those managing recruitment or job listing portals, this vulnerability poses a risk to user data confidentiality and integrity. Attackers could exploit the stored XSS to steal session cookies, impersonate users, or perform unauthorized actions within the CMS or connected systems. This could lead to data breaches, reputational damage, and potential regulatory non-compliance under GDPR if personal data is compromised. Although the vulnerability does not affect system availability, the indirect consequences of compromised user accounts or data manipulation could disrupt business operations. The requirement for authentication and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks. Organizations with public-facing job modules are particularly at risk, as attackers may craft payloads targeting HR personnel or job applicants. The medium severity rating reflects a moderate risk that should be mitigated proactively to prevent escalation or chaining with other vulnerabilities.

Summary

CVE-2025-70959 is a stored cross-site scripting (XSS) vulnerability identified in the Jobs module of Tendenci CMS version 15.3.7. Stored XSS occurs when malicious scripts injected by an attacker are permanently stored on the target server, such as in a database, and then served to other users. In this case, the vulnerability allows an attacker with at least limited privileges (PR:L) to inject crafted payloads containing arbitrary web scripts or HTML into the Jobs module interface. When other users view the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The CVSS vector indicates the attack is network exploitable (AV:N), requires low attack complexity (AC:L), requires privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The underlying weakness corresponds to CWE-79, a common XSS category. The vulnerability highlights the importance of input validation and output encoding in web applications, especially in modules handling user-generated content such as job postings.
