Under certain conditions a valid SAML IdP response may be used to impersonate another Secret Server user.

This vulnerability involves an authentication bypass via spoofing in Delinea Secret Server (On-Prem). Specifically, under certain conditions, a valid SAML IdP response can be used to impersonate another user within the Secret Server environment. The vulnerability affects versions from 10.5.0 up to and including 12.1.3. The CVSS 4.0 base score is 9.5, indicating a critical severity with network attack vector, high complexity, and no privileges or user interaction required. There are no known exploits in the wild and no vendor advisory or patch links provided in the input data.

CVE-2026-15640: CWE-290 Authentication bypass by spoofing in Delinea Secret Server (On-Prem)

An attacker can craft a malicious link that, if used by a legitimate user, may cause the user's browser to run JavaScript supplied by the attacker.

This vulnerability (CWE-79) in Delinea Secret Server (On-Prem) arises from improper neutralization of input during web page generation, enabling cross-site scripting attacks. The flaw allows an attacker to craft malicious links that, if used by legitimate users, execute arbitrary JavaScript in their browsers. The affected versions are from 10.2.19 up to and including 11.9.48. The CVSS 4.0 score is 9.3, indicating a critical severity with network attack vector, low attack complexity, no privileges required, user interaction needed, and high impacts on confidentiality, integrity, and availability. No vendor advisory or patch information is provided in the input.

CVE-2026-15639: CWE-79 Improper neutralization of input during web page generation ('cross-site scripting') in Delinea Secret Server (On-Prem)

An unauthenticated user with access to Secret Server could leverage a padding oracle to decrypt or encrypt data using one of the server's cryptographic keys. The key itself is not exposed.

This vulnerability involves the use of a broken or risky cryptographic algorithm (CWE-327) in Delinea Secret Server (On-Prem). An unauthenticated attacker with access to the server can leverage a padding oracle attack to decrypt or encrypt data with one of the server's cryptographic keys. Although the key is not exposed, the ability to perform cryptographic operations without authorization poses a significant security risk. The affected versions are from 10.5.1 up to and including 12.1.3. The CVSS 4.0 score is 9.1, indicating a critical severity with network attack vector, high complexity, and no privileges or user interaction required.
