Patch & Detection Intelligence · 6 sources · Updated 3mo ago · First seen Jul 30, 2026

Spring disclosed and national cyber agencies amplified six vulnerabilities in Spring Tools that affect developer environments for the Spring Java ecosystem, including Spring Tools for Eclipse 5.2.0 and earlier and Spring Tools for VSCode, Cursor, and Theia 2.2.0 and earlier. The most serious issues include CVE-2026-47858, which can expose Spring Boot applications started with live information mode to JMX-based remote code execution, and CVE-2026-47873, where the Boot Dashboard Docker integration publishes unauthenticated JDWP and JMX ports on 0.0.0.0 instead of limiting access to loopback, potentially exposing container control interfaces to the network.
A third high-severity flaw, CVE-2026-47882, weakens Spring Boot DevTools remote restart authentication by generating the shared secret with a non-cryptographic pseudo-random number generator. Advisories also cited additional issues involving plaintext logging of proxy credentials, cleartext storage of remote secrets, and a cross-site scripting vulnerability. Italy's ACN and the Canadian Centre for Cyber Security said updates are available or pending through Spring security bulletins, with fixed versions identified as Spring Tools for Eclipse 5.3.0 and Spring Tools for VSCode, Cursor, and Theia 2.3.0, and urged organizations to upgrade affected tooling.
