Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2025-22868)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the jws package does not properly control consumption of internal resources when handling malformed tokens. A remote attacker can pass a malformed JWT token to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2025-22869)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the ssh package when handling clients that complete the key exchange slowly, or not at all. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Input validation error (CVE-ID: CVE-2025-22870)
The vulnerability allows a remote attacker to alter application's behavior.
The vulnerability exists due to insufficient validation of an IPv6 zone ID as a hostname component, when matching hosts against proxy patterns. For instance the NO_PROXY environment variable is set to "*.example.com", a request to
"[::1%25.example.com]:80` will incorrectly match and not be proxied. A remote attacker can alter application behavior and potentially gain access to sensitive information or functionality.
4) Resource exhaustion (CVE-ID: CVE-2025-30204)
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 within the parse.ParseUnverified function when parsing authorization header. A remote attacker can send a specially crafted HTTP response to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
5) 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.
