h11 0.14.0 (pypi) pkg:pypi/[email protected] OWASP Top Ten 2017 Category A9 - Using Components with Known Vulnerabilities Affected range <0.16.0 Fixed version 0.16.0 CVSS Score 9.1 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N Description A leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') Affected range <0.16.0 Fixed version 0.16.0 CVSS Score 9.1 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N EPSS Score 0.047% EPSS Percentile 14th percentile Description Impact A leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. Details HTTP/1.1 Chunked-Encoding bodies are formatted as a sequence of "chunks", each of which consists of: chunk length \r\n length bytes of content \r\n In versions of h11 up to 0.14.0, h11 instead parsed them as: chunk length \r\n length bytes of content any two bytes i.e. it did not validate that the trailing \r\n bytes were correct, and if you put 2 bytes of garbage there it would be accepted, instead of correctly rejecting the body as malformed. By itself this is harmless. However, suppose you have a proxy or reverse-proxy that tries to analyze HTTP requests, and your proxy has a different bug in parsing Chunked-Encoding, acting as if the format is: chunk length \r\n length bytes of content more bytes of content, as many as it takes until you find a \r\n For example, pound had this bug -- it can happen if an implementer uses a generic "read until end of line" helper to consumes the trailing \r\n. In this case, h11 and your proxy may both accept the same stream of bytes, but interpret them differently. For example, consider the following HTTP request(s) (assume all line breaks are \r\n): GET /one HTTP/1.1 Host: localhost Transfer-Encoding: chunked 5 AAAAAXX2 45 0 GET /two HTTP/1.1 Host: localhost Transfer-Encoding: chunked 0 Here h11 will interpret it as two requests, one with body AAAAA45 and one with an empty body, while our hypothetical buggy proxy will interpret it as a single request, with body AAAAXX20\r\n\r\nGET /two .... And any time two HTTP processors both accept the same string of bytes but interpret them differently, you have the conditions for a "request smuggling" attack. For example, if /two is a dangerous endpoint and the job of the reverse proxy is to stop requests from getting there, then an attacker could use a bytestream like the above to circumvent this protection. Even worse, if our buggy reverse proxy receives two requests from different users: GET /one HTTP/1.1 Host: localhost Transfer-Encoding: chunked 5 AAAAAXX999 0 GET /two HTTP/1.1 Host: localhost Cookie: SESSION_KEY=abcdef... ...it will consider the first request to be complete and valid, and send both on to the h11-based web server over the same socket. The server will then see the two concatenated requests, and interpret them as one request to /one whose body includes /two's session key, potentially allowing one user to steal another's credentials. Patches Fixed in h11 0.15.0. Workarounds Since exploitation requires the combination of buggy h11 with a buggy (reverse) proxy, fixing either component is sufficient to mitigate this issue.

openssl 3.5.1-r0 (apk) pkg:apk/alpine/[email protected]?os_name=alpine&os_version=3.22 Affected range <3.5.4-r0 Fixed version 3.5.4-r0 EPSS Score 0.026% EPSS Percentile 6th percentile Description Affected range <3.5.4-r0 Fixed version 3.5.4-r0 EPSS Score 0.013% EPSS Percentile 1st percentile Description Affected range <3.5.4-r0 Fixed version 3.5.4-r0 EPSS Score 0.023% EPSS Percentile 5th percentile Description

urllib3 2.3.0 (pypi) pkg:pypi/[email protected] URL Redirection to Untrusted Site ('Open Redirect') Affected range >=2.2.0 <2.5.0 Fixed version 2.5.0 CVSS Score 5.3 CVSS Vector CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N EPSS Score 0.013% EPSS Percentile 2nd percentile Description urllib3 supports being used in a Pyodide runtime utilizing the JavaScript Fetch API or falling back on XMLHttpRequest. This means you can use Python libraries to make HTTP requests from your browser or Node.js. Additionally, urllib3 provides a mechanism to control redirects. However, the retries and redirect parameters are ignored with Pyodide; the runtime itself determines redirect behavior. Affected usages Any code which relies on urllib3 to control the number of redirects for an HTTP request in a Pyodide runtime. Impact Redirects are often used to exploit SSRF vulnerabilities. An application attempting to mitigate SSRF or open redirect vulnerabilities by disabling redirects may remain vulnerable if a Pyodide runtime redirect mechanism is unsuitable. Remediation If you use urllib3 in Node.js, upgrade to a patched version of urllib3. Unfortunately, browsers provide no suitable way which urllib3 can use: XMLHttpRequest provides no control over redirects, the Fetch API returns opaqueredirect responses lacking data when redirects are controlled manually. Expect default browser behavior for redirects. URL Redirection to Untrusted Site ('Open Redirect') Affected range <2.5.0 Fixed version 2.5.0 CVSS Score 5.3 CVSS Vector CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N EPSS Score 0.019% EPSS Percentile 4th percentile Description urllib3 handles redirects and retries using the same mechanism, which is controlled by the Retry object. The most common way to disable redirects is at the request level, as follows: resp = urllib3.request("GET", "https://httpbin.org/redirect/1", redirect=False) print(resp.status) # 302 However, it is also possible to disable redirects, for all requests, by instantiating a PoolManager and specifying retries in a way that disable redirects: import urllib3 http = urllib3.PoolManager(retries=0) # should raise MaxRetryError on redirect http = urllib3.PoolManager(retries=urllib3.Retry(redirect=0)) # equivalent to the above http = urllib3.PoolManager(retries=False) # should return the first response resp = http.request("GET", "https://httpbin.org/redirect/1") However, the retries parameter is currently ignored, which means all the above examples don't disable redirects. Affected usages Passing retries on PoolManager instantiation to disable redirects or restrict their number. By default, requests and botocore users are not affected. Impact Redirects are often used to exploit SSRF vulnerabilities. An application attempting to mitigate SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain vulnerable. Remediation You can remediate this vulnerability with the following steps: Upgrade to a patched version of urllib3. If your organization would benefit from the continued support of urllib3 1.x, please contact [email protected] to discuss sponsorship or contribution opportunities. Disable redirects at the request() level instead of the PoolManager() level.

requests 2.32.3 (pypi) pkg:pypi/[email protected] Insufficiently Protected Credentials Affected range <2.32.4 Fixed version 2.32.4 CVSS Score 5.3 CVSS Vector CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N EPSS Score 0.104% EPSS Percentile 29th percentile Description Impact Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Workarounds For older versions of Requests, use of the .netrc file can be disabled with trust_env=False on your Requests Session (docs).

pip 25.2 (pypi) pkg:pypi/[email protected] Improper Link Resolution Before File Access ('Link Following') Affected range <=25.2 Fixed version Not Fixed CVSS Score 5.9 CVSS Vector CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N EPSS Score 0.018% EPSS Percentile 3rd percentile Description Summary In the fallback extraction path for source distributions, pip used Python’s tarfile module without verifying that symbolic/hard link targets resolve inside the intended extraction directory. A malicious sdist can include links that escape the target directory and overwrite arbitrary files on the invoking host during pip install. Impact Successful exploitation enables arbitrary file overwrite outside the build/extraction directory on the machine running pip. This can be leveraged to tamper with configuration or startup files and may lead to further code execution depending on the environment, but the direct, guaranteed impact is integrity compromise on the vulnerable system. Conditions The issue is triggered when installing an attacker-controlled sdist (e.g., from an index or URL) and the fallback extraction code path is used. No special privileges are required beyond running pip install; active user action is necessary. Remediation The fix, while available as a patch that can be manually applied, has not yet been put into a numbered version but is planned for 25.3. Using a Python interpreter that implements the safe-extraction behavior described by PEP 706 provides additional defense in depth for other tarfile issues but is not a substitute for upgrading pip for this specific flaw.
