Q1What is this vulnerability? (Essence + Consequences)
π **Root Cause**: **CWE-94** (Code Injection). The flaw lies in the **Echo service** failing to restrict the SPeL context. β οΈ It permits the use of **arbitrary Java classes**, bypassing security controls.
Q3Who is affected? (Versions/Components)
π¦ **Affected Products**: Spinnaker (Continuous Delivery Platform). π **Vulnerable Versions**: < 2026.1.0, < 2026.0.1, < 2025.4.2, and < 2025.3.2. β **Safe**: Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 or newer.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: With access, hackers can: 1οΈβ£ Execute **system commands** (RCE). 2οΈβ£ Read/Write **sensitive files**. π This grants full control over the underlying infrastructure running Spinnaker.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Medium**. CVSS indicates **PR:L** (Privileges Required: Low). π€ An authenticated user with low-level privileges can exploit this. No user interaction (UI:N) needed.β¦
π§ͺ **Public Exploit**: **No**. The `pocs` field is empty in the data. π« No public Proof-of-Concept (PoC) or wild exploitation code is currently available based on this report.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: 1οΈβ£ Check your Spinnaker version against the safe list. 2οΈβ£ Audit access to the **Echo service**. 3οΈβ£ Monitor for unusual SPeL payloads in API requests targeting Echo.β¦
π‘οΈ **Official Fix**: **Yes**. Patches are available in releases: **2026.1.0**, **2026.0.1**, **2025.4.2**, and **2025.3.2**. π See GitHub Security Advisories (GHSA-69rw-45wj-g4v6) for details.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: If you cannot upgrade immediately: 1οΈβ£ **Restrict network access** to the Echo service. 2οΈβ£ **Enforce strict authentication** (high-privilege accounts only).β¦
β‘ **Urgency**: **HIGH**. CVSS Score is **Critical** (likely 9.8+ based on vector). π¨ RCE and File Access risks are severe. πββοΈ **Action**: Upgrade to a patched version **immediately**. Do not delay.
