CVE-2026-58469: GNU Wget 1.25.0 Heap Buffer Underread via Metalink URL Parsing

HighCVSS 8.7 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.49% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: wget (AlmaLinux:8) 1.19.5-16.el8_10; wget (openSUSE:Leap 16.0) 1.25.0-160000.3.1; wget (openSUSE:Tumbleweed) 1.25.0-3.1.

Low priority for now. Upgrade to wget (AlmaLinux:8) 1.19.5-16.el8_10; wget (openSUSE:Leap 16.0) 1.25.0-160000.3.1; wget (openSUSE:Tumbleweed) 1.25.0-3.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the clean_metalink_string() function within src/metalink.c that allows a malicious server to trigger memory corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink URL, potentially leading to abnormal program behavior.
