Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Input validation error (CVE-ID: CVE-2022-27664)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

2) Resource exhaustion (CVE-ID: CVE-2022-41723)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.

3) Cross-site scripting (CVE-ID: CVE-2023-3978)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

4) Input validation error (CVE-ID: CVE-2025-22872)

The vulnerability allows a remote attacker to perform code injection attacks.

The vulnerability exists due to insufficient validation of tags with unquoted attribute values that end with a solidus character (/). The tokenizer can interpret such tags as self-closing, leading to content following such tags as being placed in the wrong scope during DOM construction.

5) Resource exhaustion (CVE-ID: CVE-2025-47911)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to algorithmic complexity in the html.Parse function when processing specially crafted HTML content. A remote attacker can trigger excessive CPU consumption and perform a denial of service (DoS) attack.

6) Infinite loop (CVE-ID: CVE-2025-58190)

The vulnerability allows remote attacker to cause a denial of service.

The vulnerability exists due to an infinite loop in the html.Parse function when processing specially crafted HTML content. A remote attacker can pass malicious input to the application and cause a denial of service.
