Description Srikanth Balasubramanian 2026-07-14 13:02:39 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

GNU Wget through 1.25.0, fixed in commit dd692d9, contains a heap buffer overflow vulnerability in the html_quote_string() function in src/convert.c that allows a remote attacker to trigger memory corruption by supplying a crafted HTML attribute with a large number of characters requiring entity encoding. A server-supplied HTML attribute causes a signed integer counter to overflow during output size accumulation, resulting in an undersized heap allocation and subsequent heap buffer overflow during the copy phase.
Comment 1 Michal Ruprich 2026-07-16 07:48:57 UTC 
This CVE is not applicable for wget2, only for the original GNU Wget. wget2 is a complete re-write and does not share any code with wget. Closing.
