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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

CVE published 24 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed

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 2026-10-26.

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

European organizations should immediately upgrade all instances of Plane to version 1.1.0 or later, where the vulnerability has been patched. Until upgrades are complete, organizations should implement strict input validation and sanitization on the ?next_path parameter at the web application firewall (WAF) or reverse proxy level to block URLs containing suspicious schemes such as javascript:. Employ Content Security Policy (CSP) headers to restrict the execution of inline scripts and untrusted sources, reducing the impact of potential XSS payloads. Conduct user awareness training to recognize and avoid phishing attempts that may exploit open redirects. Monitor web server and application logs for unusual redirect patterns or suspicious query parameters. Implement multi-factor authentication (MFA) for administrative accounts to mitigate privilege escalation risks. Regularly audit and review administrative settings and user privileges to detect unauthorized changes. Finally, maintain an incident response plan tailored to web application attacks to ensure rapid containment and remediation if exploitation occurs.

Description

Plane is open-source project management software. Prior to version 1.1.0, an open redirect vulnerability in the ?next_path query parameter allows attackers to supply arbitrary schemes (e.g., javascript:) that are passed directly to router.push. This results in a cross-site scripting (XSS) vulnerability, enabling attackers to execute arbitrary JavaScript in the victim’s browser. The issue can be exploited without authentication and has severe impact, including information disclosure, and privilege escalation and modifications of administrative settings. This issue has been patched in version 1.1.0.

Impact

For European organizations, this vulnerability poses significant risks, especially for those relying on the Plane project management software for critical workflows. Exploitation can lead to unauthorized access to sensitive project data, leakage of confidential information, and unauthorized administrative changes that could disrupt operations or lead to further compromise. The lack of authentication requirement means attackers can target any user, including those with elevated privileges, increasing the risk of privilege escalation. Given the collaborative nature of project management tools, a successful attack could propagate through organizational networks, affecting multiple departments. The vulnerability also facilitates phishing attacks by leveraging open redirects, increasing the likelihood of successful social engineering campaigns. Organizations in sectors such as finance, technology, and government, which often use project management tools extensively, may face heightened risks. Additionally, the potential for administrative setting modifications could undermine compliance with data protection regulations like GDPR, leading to legal and reputational consequences.

The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
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…

Base weaknessLikelihood of exploit: LowOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
