Rilevato lo sfruttamento in rete di una vulnerabilità, identificata tramite la CVE-2026-59822, in LiteLLM di BerriAI, server proxy impiegato come gateway per l'accesso a modelli linguistici di grandi dimensioni (LLM). La vulnerabilità consente a un attaccante remoto non autenticato di eludere i meccanismi di autenticazione e accedere agli strumenti MCP senza disporre di credenziali valide.
Cisco heeft 21 kwetsbaarheden verholpen in Cisco Identity Services Engine (ISE) en Cisco ISE Passive Identity Connector (ISE-PIC). De kwetsbaarheden betreffen verschillende beveiligingsproblemen in Cisco ISE en ISE-PIC, waaronder mogelijkheden voor niet-geauthenticeerde en laaggeprivilegieerde kwaadwillenden om via netwerktoegang ongeautoriseerde acties uit te voeren. De kwetsbaarheden hebben CVSS-scores variërend van middel tot kritiek. Van de in totaal 21 kwetsbaarheden zijn 13 als kritiek…
Cisco has released security updates to address a maximum-severity Identity Services Engine vulnerability that attackers are actively exploiting in the wild. [...]
Classification: Critical, Solution: Official Fix, Exploit Maturity: High, CVSSv4.0: 9.3, CVEs: CVE-2026-89026, Summary: The Issabel Framework, the web framework supporting Issabel PBX software, before commit b97dbaf contains a hard-coded HS256 JWT signing key in the pbxapi index.php file that is identical across every installation, allowing unauthenticated remote attackers to forge valid bearer tokens. Attackers can use the forged token to call the manager originate endpoint with the System…
As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) engineering teams have conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities. These vulnerabilities were found during internal testing. One of them is known to be actively exploited. For more information, see Cisco…
Cisco has confirmed that a maximum-severity authentication bypass vulnerability tracked as CVE-2026-20079 in its Secure Firewall Management Center (FMC) software is being actively exploited in attacks. [...]
Citrix har publicerat information om en kritisk sårbarhet som påverkar Citrix NetScaler ADC och NetScaler Gateway. Sårbarheten, CVE-2026-19490, har fått CVSS v.4-klassning på 9.3. [1, 2]
CERT Polska warns that attackers are actively exploiting a chain of critical MikroTik RouterOS flaws to seize control of routers exposed to the internet. Although the warning comes from Poland’s national cybersecurity response team, MikroTik routers are sold worldwide, including in the US. The vulnerabilities can affect users anywhere if their router is running a vulnerable version of RouterOS and its SSH remote-management service is accessible from the internet. Attackers are exploiting two…
MikroTik heeft meerdere kwetsbaarheden verholpen in RouterOS. De eerste kwetsbaarheid betreft een fout in de SSH-authenticatiemechanisme waarbij de exponent van RSA-sleutels niet werd geverifieerd. Hierdoor kunnen aanvallers RSA-handtekeningen vervalsen en ongeautoriseerde SSH-toegang verkrijgen. De tweede kwetsbaarheid betreft een probleem met gebruikersnamen die beginnen met een verboden teken, waardoor de trusted policy mask kan worden gemanipuleerd en privilege escalation mogelijk is binnen…
Mikrotik released a patch late last week for an already-exploited vulnerability. The vulnerability allows an SSH authentication bypass and is already being exploited. At this point, assume compromise. Attackers have been adding new accounts to affected devices to maintain access after a patch is installed. The patch will attempt to detect compromise and set the "Flagged" status. Details: https://mikrotik.com/supportsec/september-2026-vulnerability -- Johannes B. Ullrich, Ph.D. , Dean of…

Dropbox is warning some users that an unauthorized party accessed their accounts by exploiting a flaw in Lenovo's email verification process to register fraudulent Lenovo IDs. [...]
Microsoft 11. srpna 2026 vydal opravu zranitelnosti CVE-2026-62911 (CVSS 8,0), přesto téměř 22 000 veřejně dostupných Exchange serverů zůstává zranitelných. V Česku Shadowserver eviduje přibližně 300 unikátních IP adres Exchange serverů, které vyhodnocuje jako zranitelné (na jednu či více zranitelností). Zranitelnost postihuje Exchange Server 2016, 2019 a Subscription Edition a může vést až k převzetí uživatelských e-mailových schránek. Exploit je již veřejně dostupný. Verze 2016 a 2019 jsou…
Threat actors are exploiting an unauthenticated remote code execution vulnerability (CVE-2026-0768) in Langflow, an open-source framework for building AI applications, to steal credentials, tokens, and keys. [...]

Classification: Severe, Solution: Official Fix, Exploit Maturity: Proof-of-Concept, CVSSv3.1: 9.8, CVEs: CVE-2026-61979, CVE-2026-15981, Summary: The two vulnerabilities observed in exploitation attempts are tracked as CVE-2026-61979 and CVE-2026-15981 and can be chained together to bypass authentication. Because the miniOrange SAML SSO plugin accepts the signature algorithm from incoming SAML responses instead of enforcing the configured one, an attacker can leverage CVE-2026-61979 to select…
Key Takeaways We identified an exposed server that provided unusual visibility into a large-scale, multi-victim exploitation and collection operation. Artifacts on the host showed that Claude Code and OpenClaw were embedded in the operator’s day-to-day workflow, supporting troubleshooting, orchestration, and refinement of the collection pipeline. This AI-assisted workflow resulted in the modular platform Bissa scanner […] The post Bissa Scanner Exposed: AI-Assisted Mass Exploitation and…
