Lifecycle Timeline
2DescriptionCVE.org
PraisonAI before 4.6.78 contains an unauthenticated server-side request forgery vulnerability in the Jobs API /api/v1/runs endpoint. The webhook_url parameter is validated at request time but re-resolved at connection time, allowing attackers to use DNS rebinding to reach internal services with a blind SSRF attack.
AnalysisAI
Unauthenticated blind SSRF via DNS rebinding in PraisonAI before 4.6.78 allows remote attackers to reach internal services through the Jobs API /api/v1/runs endpoint without credentials. The webhook_url parameter is validated at request intake but re-resolved at connection time, creating a TOCTOU window exploitable by an attacker who controls a malicious DNS server - flipping the resolved IP from a legitimate external address to an internal target after validation passes. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The /api/v1/runs Jobs API endpoint must be network-reachable by the attacker; the CVSS 4.0 vector (AV:N/PR:N/UI:N) confirms no authentication is required and no user interaction is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 (Medium) reflects a genuine, exploitable attack path: AV:N/PR:N confirms any unauthenticated remote attacker can reach the vulnerable endpoint, and the subsequent-system impact (SC:L/SI:L) captures the ability to probe or interact with internal services. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a domain and operates a DNS server with a 1-second TTL that initially resolves to a permitted external IP. They send an unauthenticated POST to the internet-facing /api/v1/runs endpoint with webhook_url set to their malicious domain, which passes PraisonAI's validation check. … |
| Remediation | Upgrade PraisonAI to version 4.6.78 or later, which resolves the TOCTOU re-resolution flaw per the vendor security advisory GHSA-4w49-gwv8-fpjg (https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-4w49-gwv8-fpjg). … Detailed patch versions, workarounds, and compensating controls in full report. |
