Why Is GTLB Stock Up 7% After Hours Today?

Depthfirst researcher Yuhang Wu reported a GitLab remote code execution path using two long-standing memory-safety flaws in the Ruby JSON parser Oj. GitLab parses .ipynb diffs with ipynbdiff, enabling authenticated users to submit crafted notebooks that can bypass ASLR and execute commands as the git user. Affected GitLab CE/EE: 15.2.0-18.10.7, 18.11.0-18.11.4, 19.0.0-19.0.1; fixed in 18.10.8, 18.11.5, 19.0.2. Oj affected 3.13.0-3.17.1; fixed 3.17.3.

Depthfirst researcher Yuhang Wu says an exploit chain in the Oj native JSON parser can enable remote code execution on default GitLab installs. The chain combines two long-persisting memory-safety flaws in Oj used by GitLab’s ipynbdiff for .ipynb diffs. Commands run as the “git” user, potentially exposing code and secrets. GitLab patched in 19.0.2, 18.11.5, 18.10.8; GitLab.com was already fixed.

GitLab cut 350 jobs (14% of staff) while reporting record Q1 FY2027 revenue of $264.2 million, up 23% year over year and about $10 million above analysts’ estimates, according to the company.

US stocks retreated as markets scaled back hopes for US-Iran peace. US MBA mortgage applications fell 2.5% (purchase -2.9%, refi -2.3%); the 30-year fixed rate dropped 8 bp to 6.57%. The Fed Beige Book was hawkish, citing slight-to-moderate growth and higher inflation; John Williams said no rate change is needed. Traders priced a 3% chance of a 25 bp hike.
