SpiceJet Online Booking System Vulnerabilities, CVSS 7.5
Summary
CISA ICS-CERT published advisory ICSA-26-113-04 identifying two vulnerabilities in SpiceJet's Online Booking System: Authorization Bypass Through User-Controlled Key (CVE-2026-6375) and Missing Authentication for Critical Function (CVE-2026-6376), each rated CVSS v3 7.5. Successful exploitation could allow an attacker to disclose sensitive information. The affected equipment is deployed worldwide in the Transportation Systems critical infrastructure sector. CISA recommends minimizing network exposure, isolating control system networks behind firewalls, and using secure methods such as VPNs for remote access. No known public exploitation specifically targeting these vulnerabilities has been reported.

About this source
CISA's Industrial Control Systems team publishes vulnerability advisories specifically for OT, ICS, SCADA, and critical infrastructure software: Siemens, Schneider Electric, Rockwell Automation, ABB, Honeywell, Emerson, GE Digital, plus the supporting protocols. Around 65 advisories a month, each with a CVSS score, affected products, mitigation guidance, and where applicable a Known Exploited Vulnerabilities Catalog entry. ICS advisories are higher-stakes than general IT vulns: a CVSS 7 in a PLC firmware can mean physical safety risk in a factory or grid asset. Watch this if you secure industrial networks, run a SOC for a manufacturer, or advise critical infrastructure operators. GovPing publishes each advisory with the affected vendor, CVSS, and CISA link.
What changed
CISA ICS-CERT released an advisory describing two vulnerabilities in SpiceJet's Online Booking System: Authorization Bypass Through User-Controlled Key and Missing Authentication for Critical Function, both assigned CVSS v3 7.5 severity. The vulnerabilities affect all versions of the Online Booking System. Organizations operating SpiceJet systems or similar online booking platforms in the Transportation Systems sector should review network exposure, ensure control system networks are isolated from business networks and the internet, and implement VPN-based secure remote access where required. CISA also recommends performing impact analysis and risk assessment prior to deploying any defensive measures.
Affected organizations should treat this advisory as a prompt to audit network segmentation and access controls for online booking and reservation systems that may contain sensitive customer or operational data. While no active exploitation has been reported, the CVSS 7.5 rating indicates high-severity risk of information disclosure. Transportation sector operators with ICS/OT environments should ensure these systems are not accessible from the internet and are covered by existing cybersecurity policies.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
Do not click web links or open attachments in unsolicited email messages.
Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
