Scope: Unchanged
Confidentiality: High
Integrity: None
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 18 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
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
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), 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

Immediate upgrade to WeGIA version 3.4.6 or later, which contains the patch fixing the XSS vulnerability.
Implement strict input validation and output encoding on all user-supplied data, especially parameters reflected in web pages such as 'err'. Use context-aware encoding (e.g., HTML entity encoding) to prevent script injection.
Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks.
Conduct regular security code reviews and penetration testing focusing on input handling and injection flaws.
Educate users and administrators about phishing risks associated with XSS attacks and encourage cautious behavior when clicking on links from untrusted sources.
Monitor web application logs for suspicious requests targeting the vulnerable endpoint to detect potential exploitation attempts.
If upgrading immediately is not feasible, consider temporary mitigations such as web application firewall (WAF) rules to block malicious payloads targeting the 'err' parameter.

Description

WeGIA is an open source web manager with a focus on the Portuguese language and charitable institutions. A Reflected Cross-Site Scripting (XSS) vulnerability was identified in versions prior to 3.4.6 in the `personalizacao.php` endpoint of the WeGIA application. This vulnerability allows attackers to inject malicious scripts in the `err` parameter. Version 3.4.6 fixes the issue.

Impact

For European organizations, especially those operating charitable or non-profit institutions that use WeGIA, this vulnerability poses a significant risk to the confidentiality of user data. Successful exploitation could lead to session hijacking, unauthorized access to user accounts, or exposure of sensitive personal information. Given WeGIA's focus on Portuguese language users, organizations in Portugal and other Lusophone communities in Europe may be particularly affected. The reflected XSS could also be leveraged in phishing campaigns targeting employees or donors, undermining trust and potentially causing reputational damage. While the vulnerability does not directly affect system integrity or availability, the confidentiality breach could have regulatory implications under GDPR, leading to legal and financial consequences. The medium severity rating reflects the balance between ease of exploitation and the scope of impact, but the risk is heightened if the application handles sensitive donor or beneficiary data.

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 · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
