Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, AuthenticationFilter in Kestra OSS uses request.getPath().endsWith("/configs") to whitelist the public configuration endpoint from Basic Auth. Because the check is a suffix match rather than an exact path match, any API path whose last segment is configs bypasses authentication entirely. An unauthenticated remote attacker can exploit this to create and execute arbitrary workflows without credentials. Because Kestra ships with script execution plugins (plugin-script-shell, plugin-script-python, etc.) enabled by default, this directly results in unauthenticated Remote Code Execution as root inside the Kestra worker container. This vulnerability is fixed in 1.0.45 and 1.3.21.

## CISA Adds Seven Exploited Flaws as Attackers Deploy Reverse Shells and Crypto Miners
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added seven security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog after they landed in attackers' crosshairs.
The vulnerabilities are as follows -
CVE-2026-83548 (CVSS score: 10.0) - A server-side request forgery vulnerability in SonicWall SMA 1000 Appliances that could allow a remote unauthenticated attacker to gain unauthorized access to sensitive functionality and perform unauthorized operations.
CVE-2026-83549 (CVSS score: 7.8) - A post-authen

## Combined high-signal secret-discovery triage
This combined query is useful for triage dashboards or incident review because it labels each result with a detection reason. Analysts can use the DetectionReason field to quickly separate direct environment access, LiteLLM-specific secret discovery, Python database credential access, and shell-based searching.
