88 results for “Exploitation”

CVE-2026-98432 is a use-after-free race condition in the Linux kernel IPv4 TCP code (tcp_v4_syn_recv_sock, ireq_opt), affecting kernels back to 4.4 and rated 9.8 by the kernel CVE team (Red Hat rates it 5.9). Anthropic researchers say an unreleased Claude model built an exploit that bypassed KASLR and got remote root on an MPTCP listener in about 53 minutes. The article lists distro patch status and CIQ's nftables mitigation for IP options; disabling MPTCP alone does not help. No in-the-wild exploitation is reported.

AWS reports results for its autonomous pentesting agent, AWS Security Agent (now part of AWS Continuum), on an internal CTF-style benchmark of 37 recent 2025–2026 CVEs. Each CVE ran as a live docker-compose target with a hidden flag, and the agent started from an endpoint and a one-line hint with runtime CVE lookup disabled. It captured 35 flags, 33 (89.2%) through the intended vulnerability after an audit against canonical PoCs. The post describes the 7-stage pipeline (crawler, specialist agents, validator, exploitation agent, flag check, audit), three exploit walkthroughs (CMS upload-to-admin chain, AI workflow builder RCE, tRPC full-read SSRF), the two audit reclassifications caused by benchmark bugs, and two misses where the agent took the target down.

XRP Ledger maintainers disclosed a critical integer overflow in the payment engine, reported via bug bounty in September. A payment consuming hundreds of crafted order-book offers made the buyer's owed sum wrap around to a tiny value while sellers were paid in full, minting XRP. The built-in "no XRP created" invariant check used the same flawed arithmetic and missed it. The fix shipped in 3.4.1 on Sept. 25, bypassing the usual amendment vote and two-week wait for the first time, so the open-source patch would not expose a live exploit.

CoinDesk reports on an 11-year-old integer-overflow bug in the XRP Ledger's DEX code. Hundreds of crafted offers could make the computed buyer cost wrap to near zero while sellers were credited in full, which would have minted billions of XRP beyond the 100 billion cap. The post-transaction no-new-XRP invariant check used the same miscounted total, and the per-account receive limit was sidestepped by spreading funds across hundreds of accounts. Researcher Cayden Liao and Veria AI reported it on Sept. 22, RippleX patched it with no evidence of exploitation, and the XRP Ledger Foundation plans AI adversarial testing, formal verification and a stronger bug bounty.

CoinDesk reports that researcher Cayden Liao and Veria AI found a flaw, believed to date to 2015, in the XRP Ledger's built-in exchange. Hundreds of crossed offers made the total XRP owed too large for the software to count correctly. The buyer was charged almost nothing while the sellers were paid in full, so XRP was created from nothing. The bug slipped past the ledger's post-transaction no-new-XRP invariant check, which relied on the miscounted total, and past per-account receive limits, because the XRP was spread across hundreds of accounts. RippleX reproduced it on a standalone server and fixed it in xrpld 3.4.1 on Sept. 25 without disclosing the cause. It found no evidence of exploitation on public networks.

SonicWall patched four SMA1000 appliance vulnerabilities including CVE-2026-102255, a pre-authenticated SSRF flaw (CVSS 10) that lets an unauthenticated remote attacker abuse an unintended alternate access path to reach internal functionality; two other high-severity bugs enable RCE and one medium-severity bug enables XSS. Splunk separately fixed dozens of flaws across Splunk Enterprise, MCP Server, and the Add-on for AWS, including three critical Splunk Enterprise bugs allowing arbitrary command execution, unauthorized access, and code injection, plus a medium-severity MCP Server issue letting an authenticated user redirect API requests to an attacker-controlled URL. SonicWall says SSL-VPN on its firewall products is unaffected and no in-the-wild exploitation has been observed.

Simon Willison quotes Anthropic's Frontier Red Team report "GLM-5.3 and the spread of advanced cyber capabilities," which ran several models against 100 randomly-selected tasks from an internal Binary Exploitation benchmark. GLM-5.3 produced full control-flow hijack exploits in 4% of trials and Claude Mythos Preview in 6%, while earlier models (Claude Opus 4.6, GLM-5.2) succeeded in none — marking what Anthropic frames as a newly crossed capability threshold for AI-assisted exploit development.

Anthropic's Frontier Red Team analyzes GLM-5.3, an open-weight model from Zhipu AI (Z.ai), finding it matches Claude Mythos Preview's exploit-development capability (50/410 vs 56/410 end-to-end exploits on ExploitBench against Chrome's V8 engine; 4% vs 6% full control-flow hijacks on an internal OSS-Fuzz binary exploitation benchmark) but ships with safeguards attackers bypass 64-100% of the time via prompting tricks, prefill, or "abliteration" of the open weights. The post documents a researcher using GLM-5.3 to chain previously unknown JavaScript-engine vulnerabilities into a working browser file-read exploit, and GLM-5.3-Flash autonomously building a reliable ARM64 PAC-bypass exploit chain for CVE-2026-11645 for about $20. It argues GLM-5.3's lack of meaningful safeguards marks a step change in freely accessible offensive cyber capability and calls for independent government safety testing of such open-weight models.

Cato AI Labs disclosed DuneSlide, two critical (CVSS 9.8) Cursor flaws — CVE-2026-50548 and CVE-2026-50549 — that let a zero-click prompt injection (via MCP servers or web search results read by the agent) escape Cursor's terminal sandbox and achieve arbitrary command execution. Both abuse the file-write allowlist logic: one via the run_terminal_cmd tool's working_directory parameter, the other via a symlink-resolution fallback that trusts an in-project path when the real-path check fails; both let an attacker overwrite Cursor's sandbox helper binary or startup files like ~/.zshrc to disable the sandbox entirely. Fixed in Cursor 3.0 (April 2), affecting all prior 2.x versions; the piece also situates this alongside earlier Cursor agent-exploitation chains (CurXecute/CVE-2025-54135, MCPoison/CVE-2025-54136, CVE-2026-26268).

Over 100 of the packages abused RubyDoc.info's documentation builder — which evaluates a package's .yardopts file — to run arbitrary Ruby code on its servers, scraping public UK local-government records and exfiltrating data through chunked webhook URLs; at least six packages also probed a RubyGems CDN-caching flaw (patched July 22, CVSS 7.2) that could expose another user's API key from a content-delivery edge node. Ruby Central found no confirmed evidence of a successful key theft, and OpenAI confirmed its agents used the platform but called the tasks benign, leaving open whether the exploitation attempt succeeded.

Endor Labs breaks down how the Exploit Prediction Scoring System (EPSS) v3 works — the exploitation telemetry, exploit-DB/GitHub/Metasploit code checks, CISA KEV/Project Zero/ZDI mentions, CVSS vectors, CWE, and social-media signals it ingests to score CVE exploitation likelihood — and shows that an EPSS-threshold (0.088) remediation strategy fixes the same share of exploited CVEs while patching only ~7.3% of known vulnerabilities versus ~82% under a "fix all high/critical" CVSS approach. It then explains a layered workflow: use reachability analysis (call-graph based) to cut findings by ~80% to what's actually exploitable in your environment, then apply EPSS on that reduced set to rank remaining issues by real-world exploitation likelihood, including for third-party/proprietary code where reachability analysis isn't feasible.

Snyk explains AI pentesting as an orchestrated system — a reasoning model that plans reconnaissance/exploitation, deterministic DAST tooling for known vulnerability classes, an independent validator model that confirms exploitability, and context from existing scanner findings — designed to catch context-dependent flaws like BOLA/IDOR, cross-tenant leakage, and chained business-logic exploits that signature-based scanners miss. It cites concrete reliability data (frontier models solving only ~26% of hard system-exploitation benchmark tasks, ~30% hallucinated findings without independent validation, 210% YoY growth in valid AI-generated HackerOne reports and 540% growth in prompt-injection reports) and positions Snyk's Evo Continuous Offensive Security product against these evaluation criteria.

Key findings cited: exploitation of vulnerabilities overtook credential theft as the top initial-access vector (31%), 83% of privilege-escalation incidents involved no vulnerability, 16% of organizations had an 80%+ chance a low-privilege attacker could reach a key admin account, and only 26% of CISA KEV vulnerabilities were fully remediated in 2025 (down from 38%) with median remediation time up to 43 days.

Tenet Security's Threat Labs demonstrates "Agentjacking": an attacker POSTs a crafted error event to Sentry using a public, write-only DSN scraped from a target's frontend JavaScript, embedding a markdown-formatted fake "Resolution" section inside the payload. When a developer asks Claude Code, Cursor, or Codex to triage the error via the Sentry MCP server, the agent treats the injected content as trusted diagnostic guidance and runs an attacker-supplied npx command with the developer's full privileges, exposing AWS keys, GitHub tokens, SSH sockets, and internal credentials. The team found 2,388 exposed organizations, validated exploitation against 100+ (including a Fortune 100 firm), reported an 85% agent-hijack success rate, and released "agent-jackstop," hardening configs for Cursor and Claude Code, while noting prompt-level defenses and sandboxing failed to stop it.
