Attack Complexity: Low

Scope: Unchanged
Confidentiality: Low
Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 21 Sep 2022
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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.

What to do

AI-suggested

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Enforce strict session management policies in OctoPrint, including configuring session timeouts and automatic expiration after inactivity. 2) Encourage or enforce the use of HTTPS to protect session cookies from interception over the network. 3) Implement additional authentication layers such as two-factor authentication (2FA) if supported by OctoPrint or via external access controls. 4) Regularly monitor and audit active sessions and logs to detect unusual access patterns or multiple concurrent sessions from different IP addresses. 5) Educate users on the risks of session cookie theft and encourage secure practices such as logging out after use and avoiding shared or public networks when accessing OctoPrint interfaces. 6) Where possible, isolate OctoPrint instances within secure network segments and restrict access via VPN or firewall rules to trusted users only. 7) Stay updated with OctoPrint releases and community advisories for patches or security enhancements addressing session management. 8) Consider deploying web application firewalls (WAF) or endpoint detection solutions to identify and block suspicious session hijacking attempts.

Description

If an attacker comes into the possession of a victim's OctoPrint session cookie through whatever means, the attacker can use this cookie to authenticate as long as the victim's account exists.

Impact

For European organizations using OctoPrint, particularly those involved in manufacturing, prototyping, or research and development with 3D printing technology, this vulnerability poses a moderate risk. Unauthorized access to OctoPrint sessions could lead to exposure of sensitive design files or intellectual property, disruption of manufacturing workflows, and potential sabotage of printed components. While the vulnerability does not directly impact system availability, the integrity and confidentiality of printing operations could be compromised. This is especially critical for industries such as aerospace, automotive, healthcare (medical device prototyping), and defense sectors where 3D printing is increasingly integrated. Additionally, organizations with remote or distributed printing setups may be more vulnerable if session cookies are intercepted over less secure networks. The medium CVSS score reflects the limited scope and complexity of exploitation but highlights the need for vigilance given the sensitive nature of the data and operations involved.
