If the target file already exists, it is reused without validation. +A local attacker with write access to the temp directory could pre-create a malicious +file that would be loaded in place of the legitimate one. Standard usage of the Requests +library is not affected by this vulnerability. Only applications that call +`extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the library +extracts files to a non-deterministic location. If developers are unable to upgrade, +they can set `TMPDIR` in their environment to a directory with restricted write access. + +CVE: CVE-2026-25645 +Upstream-Status: Backport [https://github.com/psf/requests/commit/66d21cb07bd6255b1280291c4fafb71803cdb3b7] +Signed-off-by: Ross Burton <[email protected]> +--- + src/requests/utils.py | 13 +++++++------ + 1 file changed, 7 insertions(+), 6 deletions(-) + +diff --git a/src/requests/utils.py b/src/requests/utils.py +index d8803e6e91..54959bb8ab 100644 +--- a/src/requests/utils.py ++++ b/src/requests/utils.py +@@ -282,12 +282,13 @@ def extract_zipped_paths(path): + return path + + # we have a valid zip archive and a valid member of that archive +- tmp = tempfile.gettempdir() +- extracted_path = os.path.join(tmp, member.split("/")[-1]) +- if not os.path.exists(extracted_path): +- # use read + write to avoid the creating nested folders, we only want the file, avoids mkdir racing condition +- with atomic_open(extracted_path) as file_handler: +- file_handler.write(zip_file.read(member)) ++ suffix = os.path.splitext(member.split("/")[-1])[-1] ++ fd, extracted_path = tempfile.mkstemp(suffix=suffix) ++ try: ++ os.write(fd, zip_file.read(member)) ++ finally: ++ os.close(fd) ++ + return extracted_path + + diff --git a/meta/recipes-devtools/python/python3-requests_2.32.4.bb b/meta/recipes-devtools/python/python3-requests_2.32.4.bb index b86ecfba52..9ebdd4f08a 100644 --- a/meta/recipes-devtools/python/python3-requests_2.32.4.bb +++ b/meta/recipes-devtools/python/python3-requests_2.32.4.bb @@ -3,13 +3,12 @@ HOMEPAGE = "https://requests.readthedocs.io"; LICENSE = "Apache-2.0" LIC_FILES_CHKSUM = "file://LICENSE;md5=34400b68072d710fecd0a2940a0d1658" -SRC_URI:append:class-nativesdk = " \ - file://environment.d-python3-requests.sh \ -" +inherit pypi python_setuptools_build_meta SRC_URI[sha256sum] = "27d0316682c8a29834d3264820024b62a36942083d52caf2f14c0591336d3422" -inherit pypi python_setuptools_build_meta +SRC_URI += "file://CVE-2026-25645.patch" +SRC_URI:append:class-nativesdk = " file://environment.d-python3-requests.sh" do_install:append:class-nativesdk() { mkdir -p ${D}${SDKPATHNATIVE}/environment-setup.d -- 2.35.6
