CVE-2026-4247

CVE-2026-4247 affects FreeBSD TCP implementations (bases: 14.x, 15.x/releng) where, when a challenge ACK should be sent, tcp_respond() consumes the mbuf and can leak the mbuf if no ACK is sent. An attacker on-path or able to establish a TCP connection can craft packets that trigger a challenge AC...

CVE-2026-4247 TCP: remotely exploitable DoS vector (mbuf leak)

When a challenge ACK is to be sent tcprespond constructs and sends the challenge ACK and consumes the mbuf that is passed in. When no challenge ACK should be sent the function returns and leaks the mbuf. If an attacker is either on path with an established TCP connection, or can themselves...

CVE-2026-33285

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, LiquidJS's memoryLimit security mechanism can be completely bypassed by using reverse range expressions e.g., 100000000..1, allowing an attacker to allocate unlimited memory. Combined wit...

CVE-2026-33285

CVE-2026-33285 concerns LiquidJS (template engine for Shopify/GitHub Pages). Vulnerability: memoryLimit protection can be bypassed by reverse range expressions (e.g., (100000000..1)), allowing unbounded memory allocation. When combined with string flattening operations (e.g., replace filter), thi...

liquidjs 安全漏洞

LiquidJS is a simple, expressive, secure, and compatible JavaScript template engine developed by Jun Yang. Versions of LiquidJS prior to 10.25.1 contained a security vulnerability, which stemmed from the use of the String.prototype.replace method in the replaceFirst filter and improper memory lim...

FreeBSD : FreeBSD -- TCP: remotely exploitable DoS vector (mbuf leak) (7aa913e9-28d1-11f1-b35e-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 7aa913e9-28d1-11f1-b35e-bc241121aa0a advisory. When a challenge ACK is to be sent tcprespond constructs and sends the challenge ACK and consumes the...

AVideo vulnerable to IP Address Spoofing via Untrusted HTTP Headers in getRealIpAddr()

Summary The getRealIpAddr function in objects/functions.php trusts user-controlled HTTP headers to determine the client's IP address. An attacker can spoof their IP address by sending forged headers, bypassing any IP-based access controls or audit logging. Vulnerable Code File:...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS due to the lack of rate limiting in the login process. An attacker can exhaust server resources by sending a large number of parallel login requests via a single HTTP/2 packet, potentially causing the server to cra...

GHSA-6Q5M-63H6-5X4V LiquidJS has Exponential Memory Amplification through its replace_first Filter $& Pattern

Summary The replacefirst filter in LiquidJS uses JavaScript's String.prototype.replace which interprets $& as a backreference to the matched substring. The filter only charges memoryLimit for the input string length, not the amplified output. An attacker can achieve exponential memory amplificati...
