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...

CVE-2026-55537 PraisonAI: Webhook SSRF via DNS fail-open in `JobSubmitRequest.validate_webhook_url()` — bypass of CVE-2026-40114

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...

EUVD-2026-65443

Ech0 through 4.2.1 contains a server-side request forgery vulnerability in the validateWebhookURL function webhooksettingservice.go, which only validates literal IP addresses via net.ParseIP and fails to reject hostnames that DNS-resolve to private or internal IPs e.g., 169.254.169.254.nip.io. An...

CVE-2026-79671

Ech0 versions through 4.2.1 contain a server-side request forgery (SSRF) vulnerability in the validateWebhookURL function (webhook_setting_service.go). The validation only rejects literal IP addresses via net.ParseIP() but fails to reject hostnames that DNS-resolve to private or internal addresse...

CVE-2026-76838

Hi.Events (an open-source event management platform) is affected by a Server-Side Request Forgery (SSRF) vulnerability in its webhook handling. The NoInternalUrlRule validates a webhook destination using gethostbyname() only at registration time , but the WebhookDispatchService never revalidates ...

The vulnerability of the _validate_webhook_url() function in the mlflow/utils/validation.py file of the machine learning lifecycle management platform allows a attacker to perform an SSRF attack and gain unauthorized access to protected information.

The vulnerability of the validatewebhookurl function in the mlflow/utils/validation.py file of the machine learning lifecycle management platform is related to insufficient validation of server-side requests. Exploiting this vulnerability could allow an attacker to perform an SSRF attack and gain...

CVE-2026-51583

An issue in usememos through v0.30.0 allows a remote authenticated attacker to perform Server-Side Request Forgery SSRF via the Webhook validation mechanism in internal/webhook/validate.go, by setting a webhook target to an internal address...

EUVD-2026-55637

The webhook URL validator in website/notifications/webhooks.py uses ip.isglobal to reject non-public addresses after DNS resolution. IPv6 transition addresses NAT64 64:ff9b::/96, 6to4 2002::/16, Teredo 2001:0000::/32 are classified as globally routable by IANA, so isglobal returns True even when...

CVE-2026-71271

Memos' webhook URL validation, isReservedIP internal/webhook/validate.go, checks a candidate IP against a reservedCIDRs list that omits 0.0.0.0/8 and never calls ip.IsUnspecified — unlike the correctly implemented sibling function isInternalIP in internal/httpgetter/htmlmeta.go, which does...

CVE-2026-71271

The CVE affects Memos server webhook URL validation. The isReservedIP() check validates candidate IPs against a reservedCIDRs list that omits 0.0.0.0/8 and never calls ip.IsUnspecified(), unlike isInternalIP() which does. Linux redirects connections to 0.0.0.0 to loopback (127.0.0.1). An attacker...

CVE-2026-71250

Firefly III is reported vulnerable due to IsValidWebhookUrl.php: the validator explicitly allows any address in 127.0.0.0/8, enabling an authenticated user with webhooks enabled to configure a webhook targeting loopback services on the server. Furthermore, the validator resolves the target once v...

CVE-2026-71250 Firefly III - Webhook URL Validation Explicitly Allows Loopback and Is Bypassable via DNS Rebinding

Firefly III's webhook URL validator IsValidWebhookUrl.php filters most private/reserved IPv4 ranges but contains an explicit early-return that allows any resolved address in 127.0.0.0/8, permitting an authenticated user with webhooks enabled, which is off by default to configure a webhook targeti...

Capsule: CapsuleConfiguration NodeMetadata regex fields lack webhook validation, allowing MustCompile panic on all Node admission requests

Summary CapsuleConfiguration.Spec.NodeMetadata.ForbiddenLabels.Regex and ForbiddenAnnotations.Regex are never validated by any admission webhook. A Cluster Admin can persist a malformed regex to etcd without being blocked. Once stored, every Node CREATE, UPDATE, or PATCH request triggers...
