A remote attacker could\npossibly use this issue to cause a denial of service. (CVE-2022-27664)\n\nIt was discovered that Go Networking had quadratic complexity when\ndecoding HPACK headers in HTTP/2 streams. A remote attacker could\npossibly use this issue to cause Go Networking to use excessive\nresources, leading to a denial of service. (CVE-2022-41723)\n\nIt was discovered that Go Networking incorrectly rendered text nodes\noutside of the HTML namespace literally, causing text that should be\nescaped to not be escaped. A remote attacker could possibly use this\nissue to perform cross-site scripting attacks. (CVE-2023-3978)\n\nGuido Vranken discovered that Go Networking processed certain inputs to\nthe HTML parsing functions non-linearly with respect to their length. A\nremote attacker could possibly use this issue to cause Go Networking to\nuse excessive resources, leading to a denial of service.\n(CVE-2024-45338)\n\nSean Ng discovered that Go Networking incorrectly interpreted tags in\nforeign content with unquoted attribute values ending with a solidus\ncharacter as self-closing, which could result in content being placed\nin the wrong scope during DOM construction. A remote attacker could\npossibly use this issue to perform cross-site scripting attacks.\n(CVE-2025-22872)\n\nIt was discovered that Go Networking had quadratic parsing complexity\nwhen processing certain HTML inputs. A remote attacker could possibly\nuse this issue to cause Go Networking to use excessive resources,\nleading to a denial of service. (CVE-2025-47911)\n\nIt was discovered that Go Networking could enter an infinite loop when\nparsing certain HTML inputs. A remote attacker could possibly use this\nissue to cause Go Networking to use excessive resources, leading to a\ndenial of service. (CVE-2025-58190)\n\nIt was discovered that Go Networking incorrectly accepted\nPunycode-encoded labels that decoded to ASCII-only labels when\nprocessing internationalized domain names. A remote attacker could\npossibly use this issue to bypass access control restrictions and\nescalate privileges.
