GNU Wget does not validate the IP address provided by an FTP PASV response while operating in FTP passive mode. A malicious FTP server, or an HTTP server that redirects to an FTP URL, can exploit this behavior to redirect Wget’s data connection to an arbitrary IP address and port. This allows an attacker to forge server-side requests (SSRF) from the machine running Wget, potentially accessing localhost services or internal network resources.

According to the versions of the wget packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    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.(CVE-2026-58469)

    GNU Wget through 1.25.0, fixed in commit c2640fe, contains a heap buffer overflow vulnerability in the     convert_fname() function within src/url.c that allows remote attackers to trigger memory corruption     through a server-supplied filename requiring character set conversion. When the output buffer is too small     during iconv E2BIG reallocation, the reallocation logic miscalculates the remaining space, leading to a     heap buffer overflow that can be exploited via a maliciously crafted server response.(CVE-2026-58471)

    GNU Wget through 1.25.0, fixed in commit 43d3ba9, contains an integer overflow vulnerability in the     parse_content_range() function within src/http.c that allows server-controlled values to cause signed     integer arithmetic to overflow. Attackers can supply malicious Content-Range header values to trigger     undefined behavior and download desynchronization in the affected client.(CVE-2026-58470)

    GNU Wget does not validate the IP address provided by an FTP PASV response while operating in FTP passive     mode. A malicious FTP server, or an HTTP server that redirects to an FTP URL, can exploit this behavior to     redirect Wget's data connection to an arbitrary IP address and port. This allows an attacker to forge     server-side requests (SSRF) from the machine running Wget, potentially accessing localhost services or     internal network resources.(CVE-2026-15146)

    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.(CVE-2026-58472)

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - GNU Wget does not validate the IP address provided by an FTP PASV response while operating in FTP passive
    mode. A malicious FTP server, or an HTTP server that redirects to an FTP URL, can exploit this behavior to
    redirect Wget’s data connection to an arbitrary IP address and port. This allows an attacker to forge
    server-side requests (SSRF) from the machine running Wget, potentially accessing localhost services or
    internal network resources. (CVE-2026-15146)
