walaikum as salam brother/sister,
it depends on the ingredients in the vinegar. we have used vinegar in our foods in pakistan for decades now so vinegar is not explicitly haram but in the west it all comes down to ingredients.
the following ingredients should be avoided by all muslims:
Alcohol
Animal Shortening
Animal Fat
Bacon
Broth
Enzymes microbial enzymes are ok
Ethanol
Gelatin
Gin
Ham
L-cysteine (Synthetic and chicken/duck feather L-cysteine is hala but if from human hair its haram)
Lard
Lipase
Pepsin
Rennet (should be avoided unless from plant/synthetic/microbial means)
Rum
Stock ( A liquid made by simmering meat, fish, bones or vegetables with herbs in water, used in soups, stews, sauces)
Wine
Tallow
Vanilla Extract/Flavor( though not haram itself, its commonly dissolved in alcohol)
Whey(unless rennet used in production is plant/microbial/synthetic, Whey should be avoided because the rennet used to curd the milk could be from a non-slaughtered animal)
