🛡️ Sentinel: [MEDIUM] Fix vulnerable dependency range for cryptography

[kingkillery]

🚨 Severity: MEDIUM
💡 Vulnerability: The pyproject.toml allowed overly broad minimum versions for the cryptography dependency (>=3.1), meaning that older, vulnerable versions could potentially be resolved in consumer environments.
🎯 Impact: Projects depending on commonforms might pull in older versions of cryptography that contain known vulnerabilities (e.g. CVE-2023-23931 or CVE-2020-25659).
🔧 Fix: Bumped the minimum cryptography version to >=42.0.0 in pyproject.toml to ensure secure defaults. Also documented this insight in the Sentinel journal.
✅ Verification: Ensure the uv lock and pytest still pass without issues with the updated dependency. Tests run locally successfully.

🧩 Analysis chain

🌐 Web query:

`Verify from official sources:

1. Does cryptography 42.x support Python >=3.10?
2. Are there any known CVEs affecting cryptography 42.0.0 specifically?
3. Do common ecosystem packages (e.g., pyOpenSSL) have compatibility notes requiring a newer cryptography minimum than 42.0.0?`

💡 Result:

1. Yes. cryptography 42.x supports Python ≥3.10 (it declares Requires: Python >=3.7 and ships wheels for Python 3.10). [1]

2. Yes. At least these CVEs affect cryptography 42.0.0:

   • CVE-2024-26130 — affects cryptography >=38.0.0 and <42.0.4, so 42.0.0 is affected. [2]
   • CVE-2024-12797 — affects cryptography >=42.0.0 and <44.0.1 (specifically: vulnerable OpenSSL statically linked into the project’s wheels), so 42.0.0 is affected. [3]

3. Yes. Some common ecosystem packages require newer cryptography than 42.0.0:

   • pyOpenSSL: since 25.2.0, minimum cryptography is 45.0.7 (and 26.0.0 requires 46.0.0). [4]
   • certbot 5.4.0: requires cryptography>=43.0.0. [5]

Consider raising cryptography minimum version higher than 42.0.0.

Version 42.0.0 itself is affected by at least two known CVEs:

• CVE-2024-26130 (affects 38.0.0–42.0.3)
• CVE-2024-12797 (affects 42.0.0–44.0.0)

Additionally, common ecosystem packages already require newer versions:

• pyOpenSSL ≥25.2.0 requires cryptography≥45.0.7
• certbot 5.4.0 requires cryptography≥43.0.0

Pinning to 42.0.0 does not prevent resolution to vulnerable releases and may cause compatibility friction with dependencies.
