CVE-2019-14806 2 Opensuse, Palletsprojects 2 Leap, Werkzeug 2023-03-03 5.0 MEDIUM 7.5 HIGH
Pallets Werkzeug before 0.15.3, when used with Docker, has insufficient debugger PIN randomness because Docker containers share the same machine id.
CVE-2019-10906 5 Canonical, Fedoraproject, Opensuse and 2 more 5 Ubuntu Linux, Fedora, Leap and 2 more 2023-03-01 5.0 MEDIUM 8.6 HIGH
In Pallets Jinja before 2.10.1, str.format_map allows a sandbox escape.
CVE-2023-23934 1 Palletsprojects 1 Werkzeug 2023-02-23 N/A 3.5 LOW
Werkzeug is a comprehensive WSGI web application library. Browsers may allow "nameless" cookies that look like `=value` instead of `key=value`. A vulnerable browser may allow a compromised application on an adjacent subdomain to exploit this to set a cookie like `=__Host-test=bad` for another subdomain. Werkzeug prior to 2.2.3 will parse the cookie `=__Host-test=bad` as __Host-test=bad`. If a Werkzeug application is running next to a vulnerable or malicious subdomain which sets such a cookie using a vulnerable browser, the Werkzeug application will see the bad cookie value but the valid cookie key. The issue is fixed in Werkzeug 2.2.3.
CVE-2023-25577 1 Palletsprojects 1 Werkzeug 2023-02-23 N/A 7.5 HIGH
Werkzeug is a comprehensive WSGI web application library. Prior to version 2.2.3, Werkzeug's multipart form data parser will parse an unlimited number of parts, including file parts. Parts can be a small amount of bytes, but each requires CPU time to parse and may use more memory as Python data. If a request can be made to an endpoint that accesses ``, `request.form`, `request.files`, or `request.get_data(parse_form_data=False)`, it can cause unexpectedly high resource usage. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it. The amount of CPU time required can block worker processes from handling legitimate requests. The amount of RAM required can trigger an out of memory kill of the process. Unlimited file parts can use up memory and file handles. If many concurrent requests are sent continuously, this can exhaust or kill all available workers. Version 2.2.3 contains a patch for this issue.
CVE-2019-14322 2 Microsoft, Palletsprojects 2 Windows, Werkzeug 2023-01-31 5.0 MEDIUM 7.5 HIGH
In Pallets Werkzeug before 0.15.5, SharedDataMiddleware mishandles drive names (such as C:) in Windows pathnames.
CVE-2022-29361 1 Palletsprojects 1 Werkzeug 2022-06-07 7.5 HIGH 9.8 CRITICAL
** DISPUTED ** Improper parsing of HTTP requests in Pallets Werkzeug v2.1.0 and below allows attackers to perform HTTP Request Smuggling using a crafted HTTP request with multiple requests included inside the body. NOTE: the vendor's position is that this behavior can only occur in unsupported configurations involving development mode and an HTTP server from outside the Werkzeug project.
CVE-2020-28493 2 Fedoraproject, Palletsprojects 2 Fedora, Jinja 2022-04-08 5.0 MEDIUM 5.3 MEDIUM
This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory.
CVE-2020-28724 1 Palletsprojects 1 Werkzeug 2020-12-01 5.8 MEDIUM 6.1 MEDIUM
Open redirect vulnerability in werkzeug before 0.11.6 via a double slash in the URL.
CVE-2019-1010083 1 Palletsprojects 1 Flask 2020-08-24 5.0 MEDIUM 7.5 HIGH
The Pallets Project Flask before 1.0 is affected by: unexpected memory usage. The impact is: denial of service. The attack vector is: crafted encoded JSON data. The fixed version is: 1. NOTE: this may overlap CVE-2018-1000656.
CVE-2018-1000656 2 Netapp, Palletsprojects 4 Active Iq, Hyper Converged Infrastructure, Ontap Select Deploy Utility and 1 more 2020-06-09 5.0 MEDIUM 7.5 HIGH
The Pallets Project flask version Before 0.12.3 contains a CWE-20: Improper Input Validation vulnerability in flask that can result in Large amount of memory usage possibly leading to denial of service. This attack appear to be exploitable via Attacker provides JSON data in incorrect encoding. This vulnerability appears to have been fixed in 0.12.3. NOTE: this may overlap CVE-2019-1010083.
CVE-2016-10745 1 Palletsprojects 1 Jinja 2019-06-06 5.0 MEDIUM 8.6 HIGH
In Pallets Jinja before 2.8.1, str.format allows a sandbox escape.
CVE-2016-10516 1 Palletsprojects 1 Werkzeug 2018-02-03 4.3 MEDIUM 6.1 MEDIUM
Cross-site scripting (XSS) vulnerability in the render_full function in debug/ in the debugger in Pallets Werkzeug before 0.11.11 (as used in Pallets Flask and other products) allows remote attackers to inject arbitrary web script or HTML via a field that contains an exception message.
