Octopus Server
Monthly
Incorrect authorization validation in Octopus Server permits authenticated users holding certain scoped permission sets to execute arbitrary scripts on deployment workers, including the built-in worker that runs directly within the Octopus Server process. The flaw bypasses the permission check that should gate script execution, allowing a user to operate outside their authorized scope without possessing the required authorisation. No public exploit has been identified and the CVE is not in CISA KEV, but the low authentication barrier - any user with some scoped permissions - makes this a meaningful privilege-escalation risk in CI/CD environments where Octopus Server routinely holds deployment credentials and infrastructure access.
Sensitive deployment variables in Octopus Server can be exposed in clear-text within the deployment variable snapshot under certain unspecified circumstances, allowing authenticated users to read secrets that should remain masked. The vulnerability affects all versions of Octopus Server per CPE wildcard and carries a CVSS 4.0 score of 7.1 with high confidentiality impact. No public exploit code or active exploitation has been identified at time of analysis, and the conditional nature of the exposure suggests the blast radius is context-dependent rather than universal across all deployments.
Path traversal in Octopus Deploy allows removing files and file contents on the host through API manipulation. Enables data destruction on the deployment server.
In Octopus Deploy 2018.8.0 through 2018.9.x before 2018.9.1, an authenticated user with permission to modify deployment processes could upload a maliciously crafted YAML configuration, potentially.

Improper access control in Octopus Deploy allows an authenticated attacker with high privileges to trigger deployments without proper authorization. Affected versions include Octopus Server 2023.0.0 through 2026.1.x before 2026.1.11587 and 2026.2.0 before 2026.2.13190. No active exploitation or public exploit code is known; EPSS indicates low exploitation probability.
Stored Cross-Site Scripting in Octopus Server allows authenticated high-privilege users to embed malicious JavaScript payloads through the artifact upload mechanism, which execute in the browsers of other users who interact with the affected artifact. The CVSS 4.0 vector (PR:H, UI:A, VC:H) confirms exploitation requires elevated access and victim interaction, with the primary impact being confidentiality - likely session token or credential theft. No public exploit code exists and the vulnerability has not been added to the CISA KEV catalog at time of analysis.
Server-level configuration changes can be made by any authenticated low-privilege user in Octopus Server through a specific API endpoint that fails to enforce authorization correctly, despite returning an error response to the caller. The flaw affects multiple active release lines - 2026.1.x, 2025.4.x, and 2023.x - and carries a CVSS 4.0 score of 6.0 with high availability impact on the vulnerable system. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
