CVE-2026-3416

WSO2 products' API Publisher component used a non-cryptographic pseudorandom number generator (PRNG) to generate shared secrets for Webhook HMAC validation. Because the PRNG lacks sufficient entropy, a sophisticated attacker can predict future secrets and forge event payloads with valid HMAC sign...

CVE-2026-3416 Predictable Pseudorandom Number Generation via Webhook HMAC Secret Generation in Multiple WSO2 Products Allows Forged Event Payloads

The API Publisher component previously used a non-cryptographic pseudorandom number generator PRNG to create shared secrets for Webhook HMAC validation. This PRNG lacks sufficient entropy for security-sensitive operations, allowing a sophisticated attacker to predict future secrets. This enables...

CVE-2026-55537

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, JobSubmitRequest.validatewebhookurl accepts webhookurl when resolution raises socket.gaierror because the exception path uses except socket.gaierror: pass. JobExecutor.sendwebhook later performs a fresh lookup, allowing DNS chang...

CVE-2026-55535

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the Jobs API validatewebhookurl path fails open on socket.gaierror and does not bind the validated address to the later request. An attacker webhookurl can later resolve to 127.0.0.1, 169.254.169.254, or another internal address...

GHSA-RG5Q-PP8P-F7JM PraisonAI: Webhook SSRF via DNS fail-open in `JobSubmitRequest.validate_webhook_url()` — bypass of CVE-2026-40114

Summary praisonai/jobs/models.py::JobSubmitRequest.validatewebhookurl validates webhook URLs by resolving the hostname and checking whether the IP is private.
