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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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.

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.

What to do

AI-suggested

1. Immediately upgrade ClipBucket installations to version 5.5.2#162 or later, where the vulnerability is patched. 2. Explicitly configure the base_url parameter in ClipBucket’s configuration to a fixed, trusted domain to prevent dynamic URL construction from the Host header. 3. Implement email link validation and monitoring to detect and block password reset emails containing unexpected domains. 4. Educate users to verify URLs in password reset emails and be cautious of unsolicited password reset requests. 5. Employ multi-factor authentication (MFA) for user accounts to reduce the impact of compromised passwords. 6. Monitor logs for suspicious password reset requests and unusual account activities. 7. Consider implementing web application firewalls (WAF) rules to detect and block requests with suspicious Host headers. 8. Regularly audit and test the password recovery workflow to ensure no similar weaknesses exist.

Description

ClipBucket v5 is an open source video sharing platform. In ClipBucket version 5.5.2, a change to network.class.php causes the application to dynamically build the server URL from the incoming HTTP Host header when the configuration base_url is not set. Because Host is a client-controlled header, an attacker can supply an arbitrary Host value. This allows an attacker to cause password-reset links (sent by forget.php) to be generated with the attacker’s domain. If a victim follows that link and enters their activation code on the attacker-controlled domain, the attacker can capture the code and use it to reset the victim’s password and take over the account. This issue has been patched in version 5.5.2#162.

Impact

For European organizations using vulnerable versions of ClipBucket v5, this vulnerability poses a significant risk to user account security. Attackers can hijack user accounts by intercepting password reset tokens, potentially gaining unauthorized access to sensitive video content, user data, and administrative functions if privileged accounts are compromised. This can lead to data breaches, reputational damage, and regulatory non-compliance under GDPR due to unauthorized access to personal data. Organizations operating public-facing video sharing platforms are particularly at risk, as attackers can craft phishing campaigns with malicious password reset links. The attack requires user interaction, so social engineering is a key enabler. The compromise of user accounts could also facilitate further lateral movement or privilege escalation within the organization’s infrastructure. Although no known exploits are currently reported in the wild, the medium severity and ease of exploitation via phishing warrant urgent remediation.

Base weaknessLikelihood of exploit: HighOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
Architecture and Design
Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
Architecture and Design
Do not use standard weak security questions and use several security questions.
Architecture and Design
Make sure that there is throttling on the number of incorrect answers to a security question. Disable the password recovery functionality after a certain (small) number of incorrect guesses.
