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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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

The primary mitigation is to upgrade ClipBucket v5 installations to build 5.5.2 #146 or later, where the vulnerability has been fixed. Since no known workarounds exist, patching is critical. Additionally, organizations should enforce strict access controls to limit who can edit video and photo metadata, reducing the risk of malicious input injection. Implementing web application firewalls (WAFs) with rules to detect and block common XSS payloads in metadata fields can provide temporary protection. Regularly audit user permissions and monitor logs for unusual editing activity. Employ Content Security Policy (CSP) headers to restrict script execution sources, mitigating the impact of injected scripts. Conduct security awareness training for administrators and content editors to recognize suspicious behavior. Finally, perform periodic vulnerability scanning and penetration testing on ClipBucket deployments to detect similar injection flaws proactively.

Description

CVE-2025-62430 is a stored cross-site scripting (XSS) vulnerability in ClipBucket v5 versions prior to build 5.5.2 #146. It affects multiple video and photo metadata fields where user input is not properly sanitized, allowing malicious script injection. An attacker with edit permissions on videos or photos can inject scripts that execute when any user, including unauthenticated visitors or administrators, views the affected pages. Although HttpOnly cookies prevent direct cookie theft, the injected scripts can perform unauthorized fetch requests to sensitive admin endpoints, potentially leaking data or triggering unintended actions. The vulnerability has a CVSS score of 5.4 (medium severity) and requires user interaction to trigger. The issue is fixed in build 5.5.

Impact

For European organizations using ClipBucket v5 in versions prior to build 5.5.2 #146, this vulnerability poses a significant risk to the confidentiality and integrity of their web applications. Attackers with editing permissions can inject malicious scripts that execute in the browsers of site visitors, including administrators, potentially leading to unauthorized data access or manipulation. This can result in leakage of sensitive administrative data, unauthorized changes to content or settings, and erosion of user trust. Since the vulnerability affects publicly accessible video and photo pages, it can be exploited by unauthenticated users if they can gain editing rights, for example via compromised accounts or weak access controls. The impact is heightened in organizations that rely on ClipBucket for media sharing with sensitive or proprietary content. While availability is not directly affected, the reputational damage and potential regulatory consequences under GDPR for data breaches could be substantial. The medium CVSS score reflects moderate risk, but the ease of exploitation by insiders or compromised users increases the threat level. European entities operating media platforms or community sites using ClipBucket should consider this vulnerability a priority for remediation to prevent exploitation.
