chore(deps): bump the backend group in /backend with 3 updates

[dependabot]

Bumps the backend group in /backend with 3 updates: alembic, pyjwt and strawberry-graphql.

Updates alembic from 1.19.1 to 1.19.2

Release notes

Sourced from alembic's releases.

1.19.2

Released: September 4, 2026

changed

• [changed] [autogenerate] The autogenerate plugin for CHECK constraint detection by name, added in 1.19.0. for #508, is no longer enabled by default. It has been renamed from alembic.autogenerate.checkconstraint_byname to alembic.ext.checkconstraint_byname and no longer matches on the "alembic.autogenerate.*" wildcard, which remains the default plugin specification. The previous name will still function as well if placed in the plugins list explicitly, both to enable the plugin and within a "~" exclusion, so that an env.py written against 1.19.0 or 1.19.1 requires no change.

  The plugin is now recommended only for schemas that ensure the naming of all constraints using a client side naming convention, otherwise there's a persistent risk of false positives. See autogenerate_check_constraints for background on things to be aware of when using this plugin.

  As part of this change "type bound" CHECK constraints, which include constraints generated for the Boolean and Enum datatypes when the create_constraint parameter is set to True, are no longer ignored in the metadata side, so that normal name-based matching can occur for these constraints.

usecase

• [usecase] [autogenerate] [batch] The target of a ~sqlalchemy.schema.ForeignKey is now located using the ForeignKey.target_tokens and ForeignKey.target_table_key accessors added in SQLAlchemy 2.1, rather than by splitting the dotted string form of that target on ".". As a dot inside a schema, table or column name cannot be told apart from the separator between those names, a foreign key whose target name contained a dot was previously mis-parsed by autogenerate rendering as well as by batch migrations. The dotted string continues to be split when running against SQLAlchemy 2.0, where these accessors are not present. Thanks to Gyanu Mayank for the initial pull request.

v2.14.0 <https://github.com/jpadilla/pyjwt/compare/2.13.0...2.14.0>__

Security

- Harden HMAC key validation against public-key material supplied as JWK,
  JWKS, array, encoded, BOM-prefixed, DER, or PEM input. See
  `GHSA-r6x4-923q-g947 <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-r6x4-923q-g947>`__,
  `GHSA-ffc3-869f-jxw9 <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-ffc3-869f-jxw9>`__,
  `GHSA-p4g4-x82p-q773 <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-p4g4-x82p-q773>`__,
  and `GHSA-w2cx-738m-mc7w <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w2cx-738m-mc7w>`__.
- Reject automatic redirects when ``PyJWKClient`` fetches a JWKS, preventing
  redirected destinations from being treated as trusted key sources. See
  `GHSA-9v7f-9g4p-ffgj <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-9v7f-9g4p-ffgj>`__.
- Limit repeated JWKS refreshes caused by unknown key IDs while preserving
  normal key-rotation behavior. See
  `GHSA-2gx3-rcp4-g85q <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-2gx3-rcp4-g85q>`__.
- Handle deeply nested and malformed JWS/JWK input without uncaught recursion
  errors or whole-set parsing failures. See
  `GHSA-8wjv-2p76-3863 <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-8wjv-2p76-3863>`__
  and `GHSA-w6j9-cwv2-h6wq <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w6j9-cwv2-h6wq>`__.
- Enforce compact JWS encoding rules during decoding. See
  `GHSA-hxm8-2xgr-2p9m <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-hxm8-2xgr-2p9m>`__.
- Reject detached-payload arguments for attached JWS inputs. Thanks to `@xclow3n
  <https://github.com/xclow3n>`__ for reporting this behavior; fixed in commit
  `37b54877 <https://github.com/jpadilla/pyjwt/commit/37b54877bf7bea67e8149130e96929e3ec798122>`__.
Fixed

- Apply HMAC key validation consistently when keys are loaded through
  ``PyJWK`` and ``PyJWKClient``. See
  `GHSA-pxh4-856f-4h89 &lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-pxh4-856f-4h89&gt;`__.
- Reject empty HMAC keys when represented as JWKs.
  See `GHSA-pxh4-856f-4h89 &lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-pxh4-856f-4h89&gt;`__.
Fixed



Raise the documented PyJWTError subclass instead of leaking a

TypeError when the exp, nbf, or iat claim decodes to a

non-numeric, non-string value such as a list, dict, or null.

Looks like these dependencies are updatable in another way, so this is no longer needed.
