CVE-2026-48686 — FastNetMon: Community Edition through 1.2.9 contains a stack-based buffer overflow in the BGP NLRI
FastNetMon Community Edition through 1.2.9 contains a stack-based buffer overflow in the BGP NLRI (Network Layer Reachability Information) decoder. The function decode_bgp_subnet_encoding_ipv4_raw() in src/bgp_protocol.cpp reads prefix_bit_length directly from the BGP packet (line 99) without validating it is <= 32 for IPv4 prefixes. This value is passed to how_much_bytes_we_need_for_storing_certain_subnet_mask() which computes ceil(prefix_bit_length / 8), returning up to 32 CVSSv3.1 9.8 (CRITICAL)
CVE-2026-43935 — Prior to 2.3.4, a Host Header Injection vulnerability in the password reset page allows
e107 is a content management system (CMS). Prior to 2.3.4, a Host Header Injection vulnerability in the password reset page allows attackers to manipulate the Host header to generate password reset links pointing to attacker-controlled domains.

Perl versions through 5.43.10 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds. Perl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes. For a quantified fixed substring with a large minimum count, the byte length mincount * l could overflow SSize_t, producing an undersized SvGROW allocation; the subsequent copy writes past the end of the buffer.

Detecting Tycoon 2FA AiTM attacks across Entra ID and Google Workspace
Elastic Security Labs published comprehensive detection engineering for Tycoon 2FA, a prolific PhaaS AiTM platform that bypasses MFA on Entra ID and Google Workspace by proxying authentication flows and intercepting post-MFA session tokens. The analysis maps two distinct operational tiers on Microsoft (kit relay + operator console) versus single-tier on Google, details evasion techniques (IP filtering, DevTools blocking, per-victim encryption), and provides detection rules exploiting cross-ASN pivots, Node.js user-agent signatures, and Graph API enumeration patterns. The kit persists on Microsoft via device-PRT registration that survives standard session revocation, requiring device deletion before token invalidation.
Smart Contracts for C&C: How ClearFake Hid in Plain Sight on BSC Testnet
Trend Micro Research documented the ClearFake campaign's use of the EtherHiding technique to store malicious payloads and C&C routing instructions in BNB Smart Chain testnet smart contracts, bypassing traditional infrastructure takedown mechanisms.
