Attack Vector: Network
Attack Complexity: Low

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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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: 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 vulnerable system. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence 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.

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Until a fix is available, users should avoid interacting with untrusted web pages while logged into the Photos app. Enabling CSRF protections in the Photos app or applying any official updates from Webasyst when released is recommended.

Description

CVE-2026-116210 is a cross-site request forgery (CSRF) vulnerability in the Webasyst Framework's Photos app up to version 4.4.0. The vulnerability arises because the Photos app does not enable the framework's opt-in CSRF protection, allowing attackers to trick logged-in users into submitting forged POST requests. These requests can delete photos or modify access rights without user consent.

Impact

Successful exploitation allows remote attackers to perform unauthorized backend actions on behalf of authenticated Photos app users, including deleting photos and changing access rights. This compromises data integrity and user control over photo content within the affected Webasyst Framework versions.

Summary

The Webasyst Framework through version 4.4.0 contains a CSRF vulnerability in its Photos app component. The app fails to enable the framework's opt-in CSRF check, which allows remote attackers to craft malicious web pages that cause authenticated users to unknowingly send forged POST requests to sensitive endpoints such as photo/delete, album/save, photo/manageAccessSave, or photo/saveField. This can result in unauthorized deletion of photos and unauthorized changes to photo access permissions. The vulnerability has a CVSS 4.0 base score of 7.1, indicating a high severity level. There is no indication of known exploits in the wild or vendor-provided patches at this time.
