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 16 Nov 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

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 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-2025-13232, organizations should immediately upgrade projectsend to version r1945 or later, which contains the official patch fixing the input validation flaw. Until the upgrade is applied, administrators should implement strict Content Security Policy (CSP) headers to restrict script execution and reduce XSS impact. Input validation and output encoding should be reviewed and enhanced in any custom integrations or plugins related to the File Editor/Custom Download Aliases feature. Monitoring web server logs and user activity for suspicious requests or unusual script execution patterns can help detect exploitation attempts. User awareness training should emphasize caution when interacting with unexpected links or file downloads from projectsend portals. Additionally, consider deploying web application firewalls (WAFs) with updated signatures to detect and block known XSS payloads targeting this vulnerability. Regular vulnerability scanning and penetration testing focused on web application security will help identify residual or related issues.

Description

A flaw has been found in projectsend up to r1720. Impacted is an unknown function of the component File Editor/Custom Download Aliases. This manipulation causes cross site scripting. The attack is possible to be carried out remotely. The exploit has been published and may be used. Upgrading to version r1945 is recommended to address this issue. Patch name: 334da1ea39cb12f6b6e98dd2f80bb033e0c7b845. It is advisable to upgrade the affected component.

Impact

Organizations using projectsend versions up to r1720 are at risk of targeted or opportunistic XSS attacks that could compromise user sessions and data confidentiality. Attackers could leverage this vulnerability to steal authentication tokens, perform actions on behalf of users, or deliver further malware. While the impact does not extend to full system compromise or availability disruption, the breach of user trust and potential data leakage can have reputational and operational consequences. This is particularly critical for organizations relying on projectsend for sensitive file transfers, such as legal, financial, or healthcare sectors. The presence of a public exploit increases the likelihood of exploitation attempts, especially in environments where patching is delayed. The vulnerability’s remote exploitation capability means attackers can target organizations globally without needing internal access, increasing the attack surface. However, the requirement for user interaction somewhat limits automated mass exploitation.

Summary

CVE-2025-13232 is a cross-site scripting vulnerability affecting projectsend, an open-source file sharing application, in versions up to r1720. The vulnerability resides in an unspecified function within the File Editor/Custom Download Aliases component, which improperly sanitizes user input, allowing attackers to inject malicious JavaScript code. This flaw can be exploited remotely without authentication, though it requires user interaction to trigger the malicious payload. The vulnerability's exploitation vector is network-based with low attack complexity and no privileges required. The impact primarily affects the confidentiality and integrity of user sessions by enabling script execution in the context of the victim’s browser, potentially leading to session hijacking, credential theft, or UI manipulation. The vulnerability does not affect system availability or require special conditions such as elevated privileges or complex user actions beyond interaction with crafted content. The vendor has released a patch in version r1945, which addresses the input validation issues. The exploit code has been publicly disclosed, increasing the risk of opportunistic attacks, although no active exploitation campaigns have been reported to date.
