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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Detectable: 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-2026-26005, European organizations should immediately upgrade ClipBucket installations to version 5.5.3 or later once available, as this version addresses the SSRF vulnerability. Until patching is possible, implement strict input validation and sanitization on URLs accepted by the Remote Play feature to block internal IP ranges (e.g., RFC1918 addresses) and localhost references. Employ web application firewalls (WAFs) with custom rules to detect and block SSRF patterns targeting internal resources. Network segmentation should be enforced to isolate the ClipBucket server from sensitive internal systems, limiting the impact of SSRF exploitation. Monitor server logs for unusual outbound HTTP requests initiated by the application, which may indicate exploitation attempts. Restrict user privileges to the minimum necessary and consider disabling the Remote Play feature if not required. Conduct internal penetration testing to identify and remediate similar SSRF risks. Finally, raise user awareness about the risks of submitting untrusted URLs and maintain an incident response plan to address potential SSRF exploitation.

Description

ClipBucket v5 is an open source video sharing platform. Prior to 5.5.3 - #45, in Clip Bucket V5, The Remote Play allows creating video entries that reference external video URLs without uploading the video files to the server. However, by specifying an internal network host in the video URL, an SSRF can be triggered, causing GET requests to be sent to internal servers. An attacker can exploit this to scan the internal network. Even a regular (non-privileged) user can carry out the attack.

Impact

For European organizations, the SSRF vulnerability in ClipBucket v5 could lead to unauthorized internal network reconnaissance, exposing sensitive infrastructure details such as internal IP addresses, services, and potentially vulnerable internal applications. This exposure can facilitate subsequent targeted attacks, lateral movement, or data exfiltration attempts. Organizations in sectors relying on video sharing platforms—such as media companies, educational institutions, and public sector entities—may be particularly at risk if they use vulnerable versions of ClipBucket. The vulnerability's exploitation by non-privileged users increases the attack surface, especially in multi-tenant or public-facing environments. While the direct impact on data integrity and availability is low, the confidentiality breach could have regulatory implications under GDPR if internal network information leads to further compromise of personal data. Additionally, the SSRF could be leveraged as a stepping stone in complex attack chains, increasing overall risk. European organizations with insufficient network segmentation or weak internal access controls are more vulnerable to exploitation.
