http.cookies.Morsel.js_output() returns an inline <script> snippet and only escapes " for JavaScript string context. It does not neutralize the HTML parser-sensitive sequence </script> inside the generated script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie value.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:1818-1 advisory.

    Security issues fixed:

    - CVE-2026-1502: HTTP client proxy tunnel headers not validated for CR/LF (bsc#1261969).
    - CVE-2026-3446: base64 decoding stops at first padded quad by default and ignores other information that     could be       processed (bsc#1261970).
    - CVE-2026-3479: improper resource argument validation in `pkgutil.get_data()` can lead to path traversal     (bsc#1259989).
    - CVE-2026-4786: URLs prefixed with `%action` can pass the dash-prefix safety check and allow for command     injection       (bsc#1262319).
    - CVE-2026-6019: `BaseCookie.js_output()` does not neutralize characters in cookie values embedded in JS     (bsc#1262654).
    - CVE-2026-6100: use-after-free in `lzma.LZMADecompressor`, `bz2.BZ2Decompressor`, and `gzip.GzipFile`     when process is       under memory pressure(bsc#1262098).

    Other updates and bugfixes:

    - Rewrite structure of Python interpreter packages. `python3*` symbols should be now provided by real     python3 packages       and its subpackages instead of the virtual provides (bsc#1258364).
