CVE-2026-25645— Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function

Quick assessment

Affected
psf requests
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Requests是Python基金会的一个优雅而简单的HTTP库。通过请求，您可以非常轻松地发送HTTP / 1.1请求。无需将查询字符串手动添加到您的URL，也无需对POST数据进行表单编码。 Requests 2.33.0之前版本存在安全漏洞，该漏洞源于extract_zipped_paths函数使用可预测文件名，可能导致本地攻击者加载恶意文件。

Vulnerability Title
Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function
Source: CVE Program / CVE List V5
Vulnerability Description
Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. 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.
