CVE-2026-15640 – Authentication Bypass via SAML Impersonation – Delinea Secret Server (On-Prem) 10.5

Be the first to know when new zero-days emerge:

Summary

CVE-2026-15640 is a critical authentication bypass vulnerability in Delinea Secret Server (on-premises). Under certain conditions, a valid SAML Identity Provider (IdP) response can be manipulated or replayed to impersonate another Secret Server user, allowing an attacker to authenticate as that user without their credentials. The flaw is rated Critical, reflecting the potential for full account impersonation and unauthorized access to stored secrets.

Technical details

  • Root cause: Secret Server’s handling of SAML IdP responses does not sufficiently bind or validate the response to the intended target user under certain conditions, allowing a valid SAML assertion to be leveraged to impersonate a different account.
  • Trigger conditions: Requires that SAML-based authentication is enabled/configured for Secret Server; the attack path depends on specific conditions in how the SAML response is processed.
  • Attack vector: Network — exploitable remotely against the Secret Server web/authentication endpoint, classified under CWE-290 (Authentication Bypass by Spoofing).
  • Impact: Successful exploitation allows an attacker to impersonate another Secret Server user, potentially granting unauthorized access to that user’s privileges and any secrets/credentials they can access within the vault.

Affected software

  • Delinea Secret Server (On-Prem, Windows) — versions 10.5.0 through 12.1.3

Severity

  • CVSS v4.0 Score: 9.5 (Critical)
  • Vector: CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:H

Mitigation and recommended actions

  • Immediate: Upgrade Delinea Secret Server (On-Prem) to version 12.2.7 or later, which resolves this vulnerability.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
