Lemur: SSRF protection in certificate revocation checking bypassable via HTTP redirects and DNS rebinding (incomplete fix for GHSA-54vg-pfh7-jq95)

SummaryThe SSRF mitigation added for GHSA-54vg-pfh7-jq95 validaterevocationurl in lemur/certificates/verify.py can be bypassed. An operator-role user who uploads a certificate with attacker-controlled CRL/OCSP extensions can still make Lemur reach internal destinations RFC1918, loopback, link-loc...

PYSEC-2026-3678 Lemur: Any user can revoke arbitrary certificates at the CA by uploading a duplicate record and revoking it

Summary Repo under test: https://github.com/Netflix/lemur PUT /api/1/certificates//revoke authorizes the caller against the Lemur database row creator == current user, or CertificatePermission over the row's roles rather than the underlying CA-side certificate identity. Separately, POST...

PYSEC-2026-3673 Lemur: Missing authorization check on POST /certificates/<id>/export for plugins with requires_key = False

Summary The CertificateExport handler in lemur/certificates/views.py nests its entire ownership / CertificatePermission check inside an if plugin.requireskey: branch. When the selected export plugin advertises requireskey = False, the authorization check is skipped entirely and any authenticated...

PYSEC-2026-3677 Lemur: Sub-CA creation never checks `AuthorityPermission` on the parent authority

Summary Repo under test: https://github.com/Netflix/lemur When ADMINONLYAUTHORITYCREATION=False an explicitly supported and documented configuration, POST /api/1/authorities with type=subca never verifies that the caller holds AuthorityPermission on the supplied parent authority. The parent field...

PYSEC-2026-3674 Lemur: Authenticated low-privilege users can read plaintext destination credentials (SFTP password / private-key passphrase) via the destinations API

Summary Lemur's destination read endpoints -- GET /api/1/destinations and GET /api/1/destinations/ -- return the full set of stored plugin option values to any authenticated user, with no authorization check and no redaction of secret-bearing options. The sibling write endpoints POST/PUT/DELETE a...

PYSEC-2026-3675 Lemur: Unchecked `replaces[]` lets any user silence notifications and hijack auto-rotation for arbitrary certificates

Summary Repo under test: https://github.com/Netflix/lemur The certificate create and upload endpoints accept a replaces alias replacements array that is resolved to live Certificate ORM objects with no ownership or CertificatePermission check on the referenced certificates. The SQLAlchemy...

MobSF Vulnerable to Arbitrary File Read via Path Traversal in ZIP Uploads

SummaryThe findiconpathzip function in MobSF does not properly sanitize the android:icon attribute extracted from an Android manifest before resolving it as a filesystem path.An attacker can supply a malicious android:icon value containing path traversal sequences, causing MobSF to read arbitrary...

sqlparse: TokenList.__init__ materializes O(subtree) value per group, causing CPU DoS before depth/token caps trigger

Summarysqlparse ships hard limits MAXGROUPINGDEPTH=100, MAXGROUPINGTOKENS=10000 intended to bound parsing work on attacker-supplied SQL, but the path that reaches those limits is itself Ondepth per token-group construction. A 1-2 KB SQL payload e.g. SELECT 1 ... with 500-2000 nesting levels, or a...

MobSF Vulnerable to Zip Bomb Denial of Service via Per-File Size Limit Bypass in ZIP/APK Extraction

SummaryWhen extracting uploaded ZIP/APK files, MobSF checks if individual files exceed ZIPMAXUNCOMPRESSEDFILESIZE 400 MB and logs "Skipping" — but the code lacks a continue statement, so extraction proceeds anyway. The log message is misleading; the file is still written to disk. Verified Impact...

PYSEC-2026-3698 sqlparse: Inefficient Regex Handling of Dollar-Quoted SQL Literals Leads to ReDoS (Denial of Service)

Summary sqlparse contains a Regular Expression Denial of Service ReDoS vulnerability in its dollar-quoted SQL literal lexer. The regex pattern at sqlparse/keywords.py:33 uses a backreference \1 to match closing dollar-quote delimiters, causing On² CPU complexity when processing inputs containing...
