GHSA-35W5-PCW4-JX94

PraisonAI: Unauthenticated Event Injection via SSE /publish Endpoint

An attacker with access to the SSE server port (default 8765, bound to 127.0.0.1 by default per DEFAULT_HOST at line 21) can:

• Inject arbitrary events into the SSE stream, potentially causing connected client applications to process malicious data, trigger actions, or display misleading content
• Leak server configuration including number of connected clients and server settings via /info
• Use the response to confirm connected client count, enabling reconnaissance

While the default binds to localhost, deployments in containers or cloud environments commonly override the host to 0.0.0.0 to allow external access. When the host is overridden, this is exploitable from the network without authentication.

A critical operation is accessible without requiring any authentication. Typical impact: any user can invoke the privileged function.

GHSA-35W5-PCW4-JX94 has a CVSS score of 4.3 (Medium). The vector is reachable from an adjacent network, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.6.59); upgrading removes the vulnerable code path.

1. What is GHSA-35W5-PCW4-JX94? GHSA-35W5-PCW4-JX94 is a medium-severity missing authentication for critical function vulnerability in praisonaiagents (pip), affecting versions <= 1.6.48. It is fixed in 1.6.59. A critical operation is accessible without requiring any authentication.
2. How severe is GHSA-35W5-PCW4-JX94? GHSA-35W5-PCW4-JX94 has a CVSS score of 4.3 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of praisonaiagents are affected by GHSA-35W5-PCW4-JX94? praisonaiagents (pip) versions <= 1.6.48 is affected.
4. Is there a fix for GHSA-35W5-PCW4-JX94? Yes. GHSA-35W5-PCW4-JX94 is fixed in 1.6.59. Upgrade to this version or later.
5. Is GHSA-35W5-PCW4-JX94 exploitable, and should I be worried? Whether GHSA-35W5-PCW4-JX94 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-35W5-PCW4-JX94 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-35W5-PCW4-JX94? Upgrade praisonaiagents to 1.6.59 or later.
