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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within 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.

Exploited in the wildExploited: no evidence on record.

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

To mitigate CVE-2025-41113, organizations should immediately audit and update the authorization logic in the CanalDenuncia.app backend API, ensuring that every request to '/backend/api/buscarDenunciaByPin.php' verifies the requesting user's permissions against the 'id_denuncia' resource. Implement role-based access control (RBAC) or attribute-based access control (ABAC) mechanisms to enforce strict data access policies. Conduct thorough code reviews and penetration testing focused on authorization checks across all API endpoints. Monitor application logs for unusual access patterns or repeated requests with varying 'id_denuncia' values that could indicate exploitation attempts. If possible, restrict API access to authenticated and authorized users only, and implement rate limiting to reduce brute-force attempts. Engage with the vendor or development team to obtain or develop patches addressing the vulnerability. Additionally, educate users and administrators about the risks of unauthorized data access and establish incident response plans to quickly address potential data breaches. Finally, ensure compliance with GDPR by notifying affected individuals and authorities if a breach occurs.

Description

A lack of authorisation vulnerability has been detected in CanalDenuncia.app. This vulnerability allows an attacker to access other users' information by sending a POST through the parameter 'id_denuncia' in '/backend/api/buscarDenunciaByPin.php'.

Impact

The primary impact of CVE-2025-41113 is the unauthorized disclosure of sensitive user information managed by CanalDenuncia.app. For European organizations, this can lead to severe privacy breaches, especially since whistleblowing platforms often handle confidential and legally sensitive reports. Exposure of such data can result in reputational damage, loss of stakeholder trust, and potential legal penalties under GDPR and other data protection laws. The vulnerability's exploitation requires no authentication, making it accessible to any remote attacker, increasing the risk of widespread data leaks. Additionally, the breach of whistleblower anonymity or sensitive complaint details could discourage reporting of wrongdoing, undermining organizational compliance and governance efforts. The lack of known exploits currently limits immediate risk, but the vulnerability's simplicity and high impact make it a prime target for attackers once exploit code becomes available. European entities relying on CanalDenuncia.app for regulatory compliance or internal reporting are particularly vulnerable to these impacts.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
