Summary

CERT-FR issued a critical security advisory on April 24, 2026 detailing 8 vulnerabilities (CVE-2026-40970 through CVE-2026-40977) in Spring Boot framework affecting versions 2.7.x prior to 2.7.33, 3.3.x prior to 3.3.19, 3.4.x prior to 3.4.16, 3.5.x prior to 3.5.14, and 4.0.x prior to 4.0.6. The vulnerabilities allow remote code execution, data confidentiality breaches, and data integrity compromise. Organizations are directed to consult Spring's security bulletins for patches.

“De multiples vulnérabilités ont été découvertes dans Spring Boot. Certaines d'entre elles permettent à un attaquant de provoquer une exécution de code arbitraire à distance, une atteinte à la confidentialité des données et une atteinte à l'intégrité des données.”

— CERT-FR , verbatim from source
Why this matters

Any organization running Spring Boot in production environments should inventory their deployed versions and prioritize patching to at least 2.7.33, 3.3.19, 3.4.16, 3.5.14, or 4.0.6 respectively. Because the advisory lists remote code execution as a confirmed risk, organizations unable to patch immediately should consider network-level isolation of affected services as a compensating control pending vendor patch availability.

About this source

CERT-FR is the French government's national cybersecurity incident response team, run by the ANSSI. Their advisory feed publishes vulnerability disclosures, active exploitation warnings, and emergency patching guidance for software in widespread enterprise use: browsers, hypervisors, ERP systems, network equipment, file transfer products. Around 180 advisories a month. The advisories are written in French but cover the same vulnerability universe as CISA, NCSC-UK, BSI's CERT-Bund, and JPCERT, often hours earlier on European-headquartered vendors. Watch this if you patch enterprise software, run a SOC, write detection content, or track Schneider, Dassault, OVH, Atos, or any French-vendor advisory faster than English-language sources will surface it. GovPing publishes each advisory with the affected vendor, severity, and CERT-FR link.

What changed

CERT-FR published a critical vulnerability advisory covering 8 CVEs in Spring Boot across five version branches (2.7.x, 3.3.x, 3.4.x, 3.5.x, and 4.0.x). The most severe risks include arbitrary remote code execution and complete compromise of data confidentiality and integrity.

Organizations running any affected Spring Boot version should immediately reference the vendor security bulletins at spring.io/security and apply the appropriate patches (versions 2.7.33, 3.3.19, 3.4.16, 3.5.14, or 4.0.6 as applicable). Given the remote code execution vector, unpatched instances should be treated as actively exposed until remediation is confirmed.
