What did CBSE say on alleged security breach?
In a message on X, the CBSE said, “In a post made by a user on social media, it has been claimed that the CBSE On Screen Marking (OSM) bearing URL: http://cbse.onmarks.co.in was compromised by him on February 26, 2026. This has also formed the basis for a few news articles.”
“At the outset, it is clarified that the Portal used for evaluation of answer-books bore a different URL, which has neither been compromised nor does it have the vulnerabilities indicated in the said social media post,” it said.
“The URL: http://cbse.onmarks.co.in is the testing site only with sample data for internal testing and review purposes. There are no actual evaluation data, marks or other data held on that portal. The Board emphasises that no security breaches have come to light on the Portal deployed for the actual evaluation work,” said the Board.
The Board would like to state that this system has been implemented for enhanced transparency in assessments with strong grievance redressal mechanisms built into it, and would reassure all concerned about the strong safeguards implemented to ensure the integrity of the platform actually deployed as regards any vulnerabilities.
Earlier in the day, Congress General Secretary K.C. Venugopal wrote to Prime Minister Narendra Modi, highlighting the “discrepancies” arising from the On-Screen Marking (OSM) introduced by the CBSE for Class 10 and 12, demanding a one-time redressal for the impacted students.
