popt-devel: popt-static: Off-by-one in poptStuffArgs

A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacke...

CVE-2026-74305

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability allows a program without cgroup storage to bypass compatibility checks when bridging tail call chains. This could enable unintended interactions between programs with and without cgroup storage,...

devpi-server may leak database contents

ImpactIf the replication protocol is enabled by using the primary or deprecated master role for a server instance, then the +changelog URL route can be used to read the complete database content including password hashes, and the ids and salts of tokens from devpi-tokens by using a trivially...

PYSEC-2026-3682 linuxfabrik-lib: Arbitrary root file read via live --test argument (lib.lftest) across sudoers-whitelisted plugins (LPE)

Summary Every Linuxfabrik check plugin that supports the shared --test argument routed through lib.lftest.test will, when --test is supplied, treat the first CSV element as a filesystem path and read its full contents as the plugin's simulated STDOUT — running as root when the plugin is invoked...

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-2026-3680 Lemur: Server-Side Request Forgery via the ACME client following server-controlled URLs

Summary The ACME client used to issue certificates from Let's Encrypt / Google Public CA / private ACME CAs connects to an acmeurl, then issues requests to URLs that the ACME server returns in its directory/order/authorization/finalize responses - this is the classic ACME-client SSRF RFC 8555...

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-2026-3679 Lemur: Incomplete fix for GHSA-v2wp-frmc-5q3v -- ACME authority update endpoint allows non-admin to replace `acme_url` with internal IP, bypassing allowlist

Summary The fix for GHSA-v2wp-frmc-5q3v added validateacmeurl to reject acmeurl values not in ACMEDIRECTORYHOSTALLOWLIST, but the validation is only called at authority creation time POST. The authority update endpoint PUT /api/1/authorities/ accepts and stores arbitrary options -- including a...

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...

PYSEC-2026-3691 MobSF Vulnerable to Zip Bomb Denial of Service via Per-File Size Limit Bypass in ZIP/APK Extraction

Summary When 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...
