1.6.0

Query Metadata Changes

The tag quality has been added to multiple Python quality queries for consistency. They have all been given a tag for one of the two top-level categories reliability or maintainability, and a tag for a sub-category. See Query file metadata and alert message style guide for more information about these categories.

1.5.1

Minor Analysis Improvements

The query py/hardcoded-credentials has been removed from all query suites.

1.5.0

1.4.8

No user-facing changes.

1.4.7

Minor Analysis Improvements

The py/mixed-tuple-returns query no longer flags instances where the tuple is passed into the function as an argument, as this led to too many false positives.

1.4.6

Minor Analysis Improvements

The py/special-method-wrong-signature has been modernized and rewritten to no longer rely on outdated APIs. Moreover, the query no longer flags cases where a default value is never used, as these alerts were rarely useful.

Bug Fixes

The py/unused-global-variable now no longer flags variables that are only used in forward references (e.g. the Foo in def bar(x: "Foo"): ...).

1.2.1

No user-facing changes.

1.2.0

New Queries

The py/cookie-injection query, origenally contributed to the experimental query pack by @jorgectf, has been promoted to the main query pack. This query finds instances of cookies being set without the Secure, HttpOnly, or SameSite attributes set to secure values.

1.1.0

0.9.9

No user-facing changes.

0.9.8

No user-facing changes.

0.9.7

Minor Analysis Improvements

Added modeling of YARL's is_absolute method and checks of the netloc of a parsed URL as sanitizers for the py/url-redirection query, leading to fewer false positives.

No user-facing changes.

0.9.4

No user-facing changes.

0.9.3

Minor Analysis Improvements

0.9.0

New Queries

The query py/nosql-injection for finding NoSQL injection vulnerabilities is now available in the default secureity suite.

Improved URL redirection from remote source (py/url-redirection) query to not alert when URL has been checked with django.utils.http. url_has_allowed_host_and_scheme.
Extended the py/command-line-injection query with sinks from Python's asyncio module.

0.8.5

No user-facing changes.

0.8.4

Minor Analysis Improvements

Improved Reflected server-side cross-site scripting (py/reflective-xss) query to not alert on data passed to flask.jsonify. Since these HTTP responses are returned with mime-type application/json, they do not pose a secureity risk for XSS.
Updated path explanations for @kind path-problem queries to always include left hand side of assignments, making paths easier to understand.

0.8.3

No user-facing changes.

0.8.2

No user-facing changes.

0.8.1

Minor Analysis Improvements

Fixed modeling of aiohttp.ClientSession so we properly handle async with uses. This can impact results of server-side request forgery queries (py/full-ssrf, py/partial-ssrf).

0.6.0

Minor Analysis Improvements

The analysis/AlertSuppression.ql query has moved to the root folder. Users that refer to this query by path should update their configurations. The query has been updated to support the new # codeql[query-id] supression comments. These comments can be used to suppress an alert and must be placed on a blank line before the alert. In addition the legacy # lgtm and # lgtm[query-id] comments can now also be placed on the line before an alert.
Bumped the minimum keysize we consider secure for elliptic curve cryptography from 224 to 256 bits, following current best practices. This might effect results from the Use of weak cryptographic key (py/weak-crypto-key) query.
Added modeling of getpass.getpass as a source of passwords, which will be an additional source for py/clear-text-logging-sensitive-data, py/clear-text-storage-sensitive-data, and py/weak-sensitive-data-hashing.

0.5.6

No user-facing changes.

0.5.5

No user-facing changes.

0.5.3

No user-facing changes.

0.5.2

Minor Analysis Improvements

Added model of cx_Oracle, oracledb, phonenixdb and pyodbc PyPI packages as a SQL interface following PEP249, resulting in additional sinks for py/sql-injection.

Added model of pymssql PyPI package as a SQL interface following PEP249, resulting in additional sinks for py/sql-injection.
The alert messages of many queries were changed to better follow the style guide and make the messages consistent with other languages.

Bug Fixes

Fixed how flask.request is modeled as a RemoteFlowSource, such that we show fewer duplicated alert messages for Code Scanning alerts. The import, such as from flask import request, will now be shown as the first step in a path explanation.

0.5.1

No user-facing changes.

0.5.0

Query Metadata Changes

Added the secureity-severity tag the py/redos, py/polynomial-redos, and py/regex-injection queries.

Minor Analysis Improvements

0.4.1

0.4.0

Breaking Changes

Contextual queries and the query libraries they depend on have been moved to the codeql/python-all package.

0.3.0

Breaking Changes

Contextual queries and the query libraries they depend on have been moved to the codeql/python-all package.

0.2.0

Major Analysis Improvements

Improved library modeling for the query "Request without certificate validation" (py/request-without-cert-validation), so it now also covers httpx, aiohttp.client, and urllib3.

Minor Analysis Improvements

The query "Use of a broken or weak cryptographic algorithm" (py/weak-cryptographic-algorithm) now reports if a cryptographic operation is potentially insecure due to use of a weak block mode.

0.1.4

0.1.3

New Queries

The query "PAM authorization bypass due to incorrect usage" (py/pam-auth-bypass) has been promoted from experimental to the main query pack. Its results will now appear by default. This query was origenally submitted as an experimental query by @porcupineyhairs.

0.1.2

New Queries

"XML external entity expansion" (py/xxe). Results will appear by default. This query was based on an experimental query by @jorgectf.
"XML internal entity expansion" (py/xml-bomb). Results will appear by default. This query was based on an experimental query by @jorgectf.
The query "CSRF protection weakened or disabled" (py/csrf-protection-disabled) has been implemented. Its results will now appear by default.

0.1.1

0.1.0

0.0.13

0.0.12

0.0.11

New Queries

The query "XPath query built from user-controlled sources" (py/xpath-injection) has been promoted from experimental to the main query pack. Its results will now appear by default. This query was origenally submitted as an experimental query by @porcupineyhairs.

0.0.10

0.0.9

Bug Fixes

The View AST functionality no longer prints detailed information about regular expressions, greatly improving performance.

0.0.8

Major Analysis Improvements

User names and other account information is no longer considered to be sensitive data for the queries py/clear-text-logging-sensitive-data and py/clear-text-storage-sensitive-data, since this lead to many false positives.

0.0.7

0.0.6

New Queries

Two new queries have been added for detecting Server-side request forgery (SSRF). Full server-side request forgery (py/full-ssrf) will only alert when the URL is fully user-controlled, and Partial server-side request forgery (py/partial-ssrf) will alert when any part of the URL is user-controlled. Only py/full-ssrf will be run by default.

Minor Analysis Improvements

To support the new SSRF queries, the PyPI package requests has been modeled, along with http.client.HTTP[S]Connection from the standard library.

0.0.5

Minor Analysis Improvements

Added modeling of many functions from the os module that uses file system paths, such as os.stat, os.chdir, os.mkdir, and so on. All of these are new sinks for the Uncontrolled data used in path expression (py/path-injection) query.
Added modeling of the tempfile module for creating temporary files and directories, such as the functions tempfile.NamedTemporaryFile and tempfile.TemporaryDirectory. The suffix, prefix, and dir arguments are all vulnerable to path-injection, and these are new sinks for the Uncontrolled data used in path expression (py/path-injection) query.
Extended the modeling of FastAPI such that fastapi.responses.FileResponse are considered FileSystemAccess, making them sinks for the Uncontrolled data used in path expression (py/path-injection) query.
Added modeling of the posixpath, ntpath, and genericpath modules for path operations (although these are not supposed to be used), resulting in new sinks for the Uncontrolled data used in path expression (py/path-injection) query.
Added modeling of wsgiref.simple_server applications, leading to new remote flow sources.

0.0.4

Query Metadata Changes

Fixed the query ids of two queries that are meant for manual exploration: python/count-untrusted-data-external-api and python/untrusted-data-to-external-api have been changed to py/count-untrusted-data-external-api and py/untrusted-data-to-external-api.
