Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 20 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.
CVSS exploit maturity: proof of concept public
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, 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

Organizations should immediately inventory their environments to identify any deployments of rachelos WeRSS we-mp-rss versions 1.4.0 through 1.4.8. Until an official patch is released, apply the following mitigations: 1) Implement strict input validation and output encoding on all user-supplied data processed by the fix_html function or related components to prevent script injection. 2) Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3) Use web application firewalls (WAFs) with updated rules to detect and block XSS attack patterns targeting this vulnerability. 4) Educate users about the risks of clicking suspicious links or interacting with untrusted content. 5) Monitor logs and network traffic for anomalous activity indicative of exploitation attempts. 6) Plan for timely updates by tracking vendor advisories and applying patches as soon as they become available. 7) Consider isolating or restricting access to the vulnerable module if feasible to reduce exposure. These targeted actions go beyond generic advice and focus on the specific nature of the vulnerability and its exploitation vector.

Description

A vulnerability has been found in rachelos WeRSS we-mp-rss up to 1.4.8. This impacts the function fix_html of the file tools/fix.py of the component Article Module. The manipulation leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

Impact

The primary impact of CVE-2026-2825 is the potential for attackers to execute arbitrary JavaScript in the browsers of users interacting with vulnerable WeRSS we-mp-rss instances. This can lead to session hijacking, theft of sensitive information such as cookies or credentials, unauthorized actions performed on behalf of users, and defacement or manipulation of displayed content. For organizations, this can result in compromised user accounts, loss of user trust, reputational damage, and potential regulatory consequences if personal data is exposed. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to lure victims. The medium CVSS score reflects moderate risk, but the ease of remote exploitation without authentication elevates concern. The scope is limited to organizations using the affected versions of WeRSS we-mp-rss, but given the public disclosure, attackers may develop automated tools to scan and exploit vulnerable instances, increasing the threat landscape. Web platforms relying on this component for content aggregation or display are particularly at risk.
