PraisonAI: Webhook signature verification skipped (fail-open) when secret unset, allowing forged inbound webhooks (WhatsApp & Linear bots)

The WhatsApp and Linear bot adapters verify the inbound webhook HMAC signature onlywhen a secret is configured. When the secret environment variable is unset — thedefault on a fresh install and common in development — verification is skipped entirelyand the webhook body is parsed and dispatched a...

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.223, an unauthenticated attacker can inject messages into any existing support conversation by sending a single email to the helpdesk's public address with a crafted In-Reply-To header. No...

CVE-2026-54736 Phalcon: Non-constant-time HMAC verification in `Encryption\Crypt::decrypt` (timing side-channel)

Phalcon is a high-performance, full-stack PHP framework. Prior to 5.14.1, Phalcon\Encryption\Crypt::decrypt compares the attacker-supplied HMAC tag against the freshly computed HMAC using PHP/Zephir identity comparison, which lowers to a byte-wise comparison that returns early on the first...

PYSEC-2026-732 Plone credentials stored in session cookie

Plone CMS 3.1.x uses invariant data a client username and a server secret when calculating an HMAC-SHA1 value for an authentication cookie, which makes it easier for remote attackers to gain permanent access to an account by sniffing the network...

CVE-2026-6331

HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...

CVE-2026-6331

CVE-2026-6331 describes an HMAC zero-length tag forgery in EVP_DigestVerifyFinal. The OpenSSL-compatibility HMAC verify path allowed a zero-length or truncated tag to pass because the signature length check only ensured it did not exceed the MAC length. The fixed behavior now requires the supplie...
