CVE-2026-39821

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname (for example, xn--example-.com returns example.com instead of an error). Applications that validate the ASCII form then convert to Unicode may grant access to a restricted hostname the ASCII check would have rejected.

CVE-2026-46595

A flaw was found in golang.org/x/crypto/ssh. Source-address validation can be skipped when an SSH server configuration uses an authentication callback type other than public key, allowing authorization bypass in misconfigured servers. This is a follow-on to incomplete coverage from the CVE-2024-45337 fix.

CVE-2026-39821 (GCVE-0-2026-39821)

Vulnerability from cvelistv5 – Published: 2026-05-22 15:01 – Updated: 2026-07-08 12:05

Title

Invoking failure to reject ASCII-only Punycode-encoded labels in golang.org/x/net/idna

Summary

The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".

CVE-2026-5497 (GCVE-0-2026-5497)

Vulnerability from cvelistv5 – Published: 2026-06-11 08:31 – Updated: 2026-07-03 12:04

Title

Unbounded Frame Count in video/jpeg Base64 Data URL Processing Leads to OOM DoS in vllm-project/vllm

Summary

vLLM versions 0.8.0 and later are vulnerable to an Out-of-Memory (OOM) Denial of Service (DoS) attack due to unbounded frame count processing in the `VideoMediaIO.load_base64()` method. When processing `video/jpeg` data URLs, the method splits the base64 data string on commas to extract individual JPEG frames without enforcing a frame count limit. An attacker can exploit this by crafting a single API request containing thousands of comma-separated base64-encoded JPEG frames in a data URL, causing the server to decode all frames into memory and crash due to excessive memory consumption. This vulnerability is reachable via the OpenAI-compatible chat completions API and does not require authentication.

When processing `video/jpeg` data URLs, the method splits the base64 data string on commas to extract individual JPEG frames without enforcing a frame count limit. An attacker can exploit this by crafting a single API request containing thousands of comma-separated base64-encoded JPEG frames in a data URL, causing the server to decode all frames into memory and crash due to excessive memory consumption. This vulnerability is reachable via the OpenAI-compatible chat completions API and does not require authentication."
