Technical description

Renovate versions from 42.68.1 before 42.96.3 and from 43.0.0 before 43.4.4, including the renovate/renovate Docker images, and Mend Renovate CE/EE images (renovate-ce, renovate-ee-server, renovate-ee-worker) from 13.3.0 before 13.6.0, fail to restrict environment variables to an allowlist when spawning child processes. As a result, child processes (e.g. npm install, postUpgradeTasks, postUpdateOptions) gain full access to all environment variables of the Renovate process, allowing insider or outside attackers to exfiltrate secrets accessible to the Renovate deployment.

——0Letta through 0.16.8 contains an information disclosure vulnerability that allows users running tools to read server secrets because LocalSandbox subprocesses inherit the full server environment. Attackers can run code via POST /v1/tools/run or custom tools to read LETTA_PG_URI, POSTGRES_PASSWORD, and provider API keys, then access cross-tenant database data.11h CVE-2026-1085925.3 MED

——7mini-swe-agent 1.10.0 through 2.4.6 contains an information exposure vulnerability in BubblewrapEnvironment because bwrap omits --clearenv, so sandboxed commands inherit the host environment. Attackers using prompt injection in processed task content can make the agent read API keys from the environment and exfiltrate them over the shared network.4d CVE-2026-726486.5 MED

——11Cleartext Storage of Sensitive Information in an Environment Variable (CWE-526) in Elastic Cloud on Kubernetes (ECK) can lead to information disclosure via Retrieve Embedded Sensitive Data (CAPEC-37). When ECK reconciles a Fleet Server resource that authenticates to Elasticsearch with a service account token, the token is written into the generated workload specification in cleartext rather than being referenced from the Kubernetes Secret that ECK maintains for the other credentials on the same path. Any principal able to read workload specifications in the affected namespace can therefore read a live Elasticsearch credential, even when Kubernetes RBAC does not grant that principal access to Secrets.46d CVE-2026-493774.3 MED

——16A vulnerability was found in Keycloak. Admin users may have to access sensitive server environment variables and system properties through user-configurable URLs. When configuring backchannel logout URLs or admin URLs, admin users can include placeholders like ${env.VARNAME} or ${PROPNAME}. The server replaces these placeholders with the actual values of environment variables or system properties during URL processing.50d
